Jan Svoboda 40c261c41c [clang][cli] Generate and round-trip language options
This patch implements generation of remaining language options and tests it by performing parse-generate-parse round trip (on by default for assert builds, off otherwise).

This patch also correctly reports failures in `parseSanitizerKinds`, which is necessary for emitting diagnostics when an invalid sanitizer is passed to `-fsanitize=` during round-trip.

This patch also removes TableGen marshalling classes from two options:
* `fsanitize_blacklist` When parsing: it's first initialized via the generated code, but then also changed by manually written code, which is confusing.
* `fopenmp` When parsing: it's first initialized via generated code, but then conditionally changed by manually written code. This is also confusing. Moreover, we need to do some extra checks when generating it, which would be really cumbersome in TableGen. (Specifically, not emitting it when `-fopenmp-simd` was present.)

Stephen Kelly d6a06365cf [ASTMatchers] Fix matching after generic top-level matcher
With a matcher like

  expr(anyOf(integerLiteral(equals(42)), unless(expr())))

and code such as

  struct B {
    B(int);
  };

  B func1() { return 42; }

the top-level expr() would match each of the nodes which are not spelled

This would result in multiple results reported for the integerLiteral.

Fix that by only running matching logic on nodes which are not skipped
with the top-level matcher.

Stephen Kelly a7101450a4 [ASTMatchers] Add mapAnyOf matcher
Make it possible to compose a matcher for different base nodes.

This accepts one or more node matcher functors and zero or more
matchers, composing the latter into the former.

This allows composing of matchers where the same inner matcher name is
used for the same concept, but with a different node functor. Currently,
there is a limitation that the nodes must be in the same "clade", so
while

  mapAnyOf(ifStmt, forStmt).with(hasBody(stmt()))

can be used, functionDecl can not be added to the tuple.

It is possible to use this in clang-query, but it will require changes
to the QueryParser, so is deferred to a future review.

Jan Svoboda 8e3230ffa3 [clang][cli] Port DiagnosticOpts to new option parsing system
This patch introduces additional infrastructure necessary to accommodate DiagnosticOptions.

DiagnosticOptions are unique in that they are parsed by the same function in cc1 AND in the Clang driver. The call to the parsing function from the driver occurs early on in the compilation process, where no proper DiagnosticEngine exists, because the diagnostic options (passed through command line) are not known yet.

To preserve the current behavior, we need to be able to selectively parse:
* all options (for -cc1),
* only diagnostic options (for driver).

This patch achieves that in the following way:
* new MacroPrefix field is added to the Option TableGen class,
* new IsDiag TableGen mixin sets MacroPrefix to "DIAG_",
* TableGen backend serializes option records into a macro with the prefix,
* CompilerInvocation parse/generate methods define the [DIAG_]OPTION_WITH_MARSHALLING macros to handle diagnostic options separately.

Depends on D93700, D93701 & D93702.

This is a tentative fix which addresses a PR raise regarding Case indentation when working with Whitesmiths Indentation

I could not find online any reference sources as to what the case indentation for Whitesmith's should be (or be allowed to be)

But according to the documentation, we don't obey the rules for Whitesmith's

```
In particular, the documentation states that this option is to "indent case labels one level from the switch statement. When false, use the same indentation level as for the switch statement."
```

The behaviour we add here is actually as the TODO in the tests used to state in {D67627}, but when {D82016} was added and I brought these tests out from being TODO I realized I changed the indentation.

Jan Svoboda 70410a2649 [clang][cli] Let denormalizer decide how to render the option based on the option class
Before this patch, you needed to use `AutoNormalizeEnumJoined` whenever you wanted to **de**normalize joined enum.
Besides the naming confusion, this means the fact the option is joined is specified in two places: in the normalization multiclass and in the `Joined<["-"], ...>` multiclass.
This patch makes this work automatically, taking into account the `OptionClass` of options.

Also, the enum denormalizer now just looks up the spelling of the present enum case in a table and forwards it to the string denormalizer.

I also added more tests that exercise this.

Jan Svoboda 95114f21f5 [clang][cli] Do not marshall only CC1Option flags in BoolOption
We cannot be sure whether a flag is CC1Option inside the definition of `BoolOption`. Take the example below:

```
let Flags = [CC1Option] in {
  defm xxx : BoolOption<...>;
}
```

where TableGen applies `Flags = [CC1Option]` to the `xxx` and `no_xxx` records **after** they have been is fully declared by `BoolOption`.

For the refactored `-f[no-]debug-pass-manager` flags (see the diff), this means `BoolOption` never adds any marshalling info, as it doesn't see either of the flags as `CC1Option`.

For that reason, we should defensively append the marshalling information to both flags inside `BoolOption`. Now the check for `CC1Option` needs to happen later, in the parsing macro, when all TableGen logic has been resolved.

However, for some flags defined through `BoolOption`, we can run into issues:

```
// Options.td
def fenable_xxx : /* ... */;

// Both flags are CC1Option, the first is implied.
defm xxx : BoolOption<"xxx,
  "Opts.Xxx", DefaultsToFalse,
  ChangedBy<PosFlag, [CC1Option], "", [fenable_xxx]>,
  ResetBy<NegFlag, [CC1Option]>>;
```

When parsing `clang -cc1 -fenable-xxx`:
* we run parsing for `PosFlag`:
  * set `Opts.Xxx` to default `false`,
  * discover `PosFlag` is implied by `-fenable-xxx`: set `Opts.Xxx` to `true`,
  * don't see `-fxxx` on command line: do nothing,
* we run parsing for `NegFlag`:
  * set `Opts.Xxx` to default `false`,
  * discover `NegFlag` cannot be implied: do nothing,
  * don't see `-fno-xxx` on command line: do nothing.

Now we ended up with `Opts.Xxx` set to `false` instead of `true`. For this reason, we need to ensure to append the same `ImpliedByAnyOf` instance to both flags.

This means both parsing runs now behave identically (they set the same default value, run the same "implied by" check, and call `makeBooleanOptionNormalizer` that already has information on both flags, so it returns the same value in both calls).

The solution works well, but what might be confusing is this: you have defined a flag **A** that is not `CC1Option`, but can be implied by another flag **B** that is `CC1Option`:
* if **A** is defined manually, it will never get implied, as the code never runs
```
def no_signed_zeros : Flag<["-"], "fno-signed-zeros">, Group<f_Group>, Flags<[]>,
  MarshallingInfoFlag<"LangOpts->NoSignedZero">, ImpliedByAnyOf<[menable_unsafe_fp_math]>;
```
* if **A** is defined by `BoolOption`, it could get implied, as the code is run by its `CC1Option` counterpart:
```
defm signed_zeros : BoolOption<"signed-zeros",
  "LangOpts->NoSignedZero", DefaultsToFalse,
  ChangedBy<NegFlag, [], "Allow optimizations that ignore the sign of floating point zeros",
            [cl_no_signed_zeros, menable_unsafe_fp_math]>,
  ResetBy<PosFlag, [CC1Option]>, "f">, Group<f_Group>;
```

This is a surprising inconsistency.

One solution might be to somehow propagate the final `Flags` of the implied flag in `ImpliedByAnyOf` and check whether it has `CC1Option` in the parsing macro. However, I think it doesn't make sense to spend time thinking about a corner case that won't come up in real code.

An observation: it is unfortunate that the marshalling information is a part of the flag definition. If we represented it in a separate structure, we could avoid the "double parsing" problem by having a single source of truth. This would require a lot of additional work though.

Note: the original patch missed the `CC1Option` check in the parsing macro, making my reasoning here incomplete. Moreover, it contained a change to denormalization that wasn't necessarily related to these changes, so I've extracted that to a follow-up patch: D93094.

            #pragma HLS UNROLL
            // clang-format on

```

can become

```
    for (int i = 0; i < 5; i++) {
        #pragma HLS UNROLL
        for (int j = 0; j < 5; j++) {

Without this fix, when we import the CXXDeductionGuideDecl (via
VisitFunctionDecl) then before creating the Decl we must import the
FunctionType. However, the first parameter's type is the afore mentioned
local typedef. So, we then start importing the TypedefDecl whose
DeclContext is the CXXDeductionGuideDecl itself. The infinite loop is
formed.

The fix is to first create the TypedefDecl and only then start to import
the DeclContext.
Basically, we could do this during the import of all other Decls (not
just for typedefs). But it seems, there is only one another AST
construct that has a similar cycle: a struct defined as a function
parameter:
```
int struct_in_proto(struct data_t{int a;int b;} *d);

```
In that case, however, we had decided to return simply with an error
back then because that seemed to be a very rare construct.

Raphael Isemann 0c926e6d24 [ASTImporter] Make the Import() return value consistent with the map of imported decls when merging ClassTemplateSpecializationDecls
When importing a `ClassTemplateSpecializationDecl` definition into a TU with a matching
`ClassTemplateSpecializationDecl` definition and a more recent forward decl, the ASTImporter
currently will call `MapImported()` for the definitions, but will return the forward declaration
from the `ASTImporter::Import()` call.

This is triggering some assertions in LLDB when we try to fully import some DeclContexts
before we delete the 'From' AST. The returned 'To' Decl before this patch is just the most recent
forward decl but that's not the Decl with the definition to which the ASTImporter will import
the child declarations.

This patch just changes that the ASTImporter returns the definition that the imported Decl was
merged with instead of the found forward declaration.

Stephen Kelly 246b428fb3 [AST] Ignore implicit nodes in IgnoreUnlessSpelledInSource mode
Update the ASTNodeTraverser to dump only nodes spelled in source.  There
are only a few which need to be handled, but Decl nodes for which
isImplicit() is true are handled together.

Update the RAV instances used in ASTMatchFinder to ignore the nodes too.
As with handling of template instantiations, it is necessary to allow
the RAV to process the implicit nodes because they need to be visitable
before the first traverse() matcher is encountered.  An exception to
this is in the MatchChildASTVisitor, because we sometimes wish to make a
node matchable but make its children not-matchable.  This is the case
for defaulted CXXMethodDecls for example.

Extend TransformerTests to illustrate the kinds of problems that can
arise when performing source code rewriting due to matching implicit
nodes.

This change accounts for handling nodes not spelled in source when using
direct matching of nodes, and when using the has() and hasDescendant()
matchers.  Other matchers such as
cxxRecordDecl(hasMethod(cxxMethodDecl())) still succeed for
compiler-generated methods for example after this change.  Updating the
implementations of hasMethod() and other matchers is for a follow-up
patch.

This ports a number of OpenCL and fast-math flags for floating point

As part of this, `Opt{In,Out}FFlag` were enhanced to allow other flags to
imply them, via `DefaultAnyOf<>`. For example:
```
defm signed_zeros : OptOutFFlag<"signed-zeros", ...,
  "LangOpts->NoSignedZero",
  DefaultAnyOf<[cl_no_signed_zeros, menable_unsafe_fp_math]>>;
```
defines `-fsigned-zeros` (`false`) and `-fno-signed-zeros` (`true`)
linked to the keypath `LangOpts->NoSignedZero`, defaulting to `false`,
but set to `true` implicitly if one of `-cl-no-signed-zeros` or
`-menable-unsafe-fp-math` is on.

Note that the initial patch was written Daniel Grumberg.
