This is a cleanup of all llvm-qualified-auto findings.
This patch was created by automatically applying the fixes from
clang-tidy.

This patch adds a forward declaraiton of DynTypedNode.
DumpAST.h is relying on the forward declaration of DynTypedNode in
ASTContext.h, which is undesirable.
LLVM Programmer’s Manual strongly discourages the use of `std::vector<bool>` and suggests `llvm::BitVector` as a possible replacement.
Currently, some users of `std::vector<bool>` cannot switch to `llvm::BitVector` because it doesn't implement the `pop_back()` and `back()` functions.
To enable easy transition of `std::vector<bool>` users, this patch implements `llvm::BitVector::pop_back()` and `llvm::BitVector::back()`.

These errors are non-harmful and should be transient. They either
imply:
- compilation database returned stale results for TUs and it'll be fixed once
it's updated to match project state.
- a TUs dependencies has changed and some headers no longer exist. this should
be fixed with the next indexing cycle.
In either case the user will have some stale symbols in their index until clangd
restarts and the underlying issue is resolved. On the downside these logs are
confusing users when there's another issue.

Targets are not necessarily inserted in the order they appear in source
code. For example we could traverse overload sets, or selectively insert
template patterns after all other decls.
So order the targets before printing to make sure tests are not dependent on
such implementation details. We can also do it in production, but that might be
wasteful as we haven't seen any complaints in the wild around these orderings
yet.

This is a follow-up on D116643. `isInSystemHeader` check already detects
symbols coming from the Standard Library, so searching for the qualified name
in StdSymbolMap.inc is no longer necessary.
The tests filtering out purely based on the symbol qualified names are removed.

Adds a option `use-dirty-preambles` to enable using unsaved in editor contents when building pre-ambles.
This enables a more seamless user experience when switching between header and implementation files and forgetting to save inbetween.
It's also in line with the LSP spec that states open files in the editor should be used instead of on the contents on disk - https://microsoft.github.io/language-server-protocol/overviews/lsp/overview/
For now the option is defaulted to off and hidden, Though I have a feeling it should be moved into the `.clangd` config and possibly defaulted to true.

The patch was reverted because it caused a crash during PCH build -- we
missed to update the RParenLoc in TreeTransform<Derived>::TransformAutoType.
This relands 55d96ac and 37ec65e with a test and fix.
This is a workaround (adding a newline to the eof) in clangd to avoid the code
completion crash, see https://github.com/clangd/clangd/issues/332.
In principle, this is a clang bug, we should fix it in clang, but it is not
trivial.

During pop() we convert nodes into spans of expanded syntax::Tokens.
If we precompute a range of plausible (expanded) tokens, then we can do an
extremely cheap approximate hit-test against it, because syntax::Tokens are
ordered by pointer.
This would seem not to buy anything (we don't enter nodes unless they overlap
the selection), but in fact the spans we have are for *newly* claimed ranges
(i.e. those unclaimed by any child node).
So if you have:
{ { [[2+2]]; } }
then all of the CompoundStmts pass the hit test and are pushed, but we skip
full hit-testing of the brackets during pop() as they lie outside the range.
This is ~10x average speedup for selectiontree on a bad case I've seen
(large gtest file).

Not sure it's OK to suppress this in clang itself - if we're building a PCH

The AST doesn't track their locations, and the default behavior of attributing
them to the lexically-enclosing node is sloppy and often inaccurate.
Also add a couple of passing test cases for declarators that weren't obvious.
Differential Revision: https://reviews.llvm.org/D117185
When searching for AST nodes that may overlap the selection, mayHit() was only
attempting to prune nodes whose begin/end are both in the main file.
While failing to prune never gives wrong results, it hurts performance.
In GTest unit-tests, `TEST()` macros at the top level declare classes.
These were never pruned and we traversed *every* such class for any selection.
We fix this by reasoning about what tokens such a node might claim.
They must lie within its ultimate macro expansion range, so if this doesn't
overlap with the selection, we can prune the node.

New values:
- Split Dynamic into Open/Preamble
- Add Background (previously was just Unknown)
- Soon: stdlib index
This requires extending to 16 bits, which fits within the padding of Symbol.
Unfortunately we're also *serializing* SymbolOrigin as a fixed 8 bits.
Stop serializing SymbolOrigin:
- conceptually, the source is whoever indexes or *deserializes* a symbol
- deserialization takes SymbolOrigin as a parameter and stamps it on each sym
- this is a breaking format change

C++ member function bodies (including ctor initializers) are first captured
into a buffer and then parsed after the class is complete. (This allows
members to be referenced even if declared later).
When the boundary of the function body cannot be established, its buffer is
discarded and late-parsing never happens (it would surely fail).
For code completion this is the wrong tradeoff: the point of the parse is to
generate completions as a side-effect.
Today, when the ctor body wasn't typed yet there are no init list completions.
With this patch we parse such an init-list if it contains the completion point.
There's one caveat: the parser has to decide where to resume parsing members
after a broken init list. Often the first clear recovery point is *after* the
next member, so that member is missing from completion/signature help etc. e.g.
struct S {
S() m //<- completion here
int maaa;
int mbbb;
}
Here "int maaa;" is treated as part of the init list, so "maaa" is not available
as a completion. Maybe in future indentation can be used to recognize that
this is a separate member, not part of the init list.

std::remove from algorithm is a lot more common than the overload from

Often we run into situations where we want to ignore
warnings from system headers, but Clang will still
give warnings about the contents of a macro defined
in a system header used in user-code.
Introduce a ShowInSystemMacro option to be able to
specify which warnings we do want to keep raising
warnings for. The current behavior is kept in this patch
(i.e. warnings from system macros are enabled by default).
The decision as to whether this should be an opt-in or opt-out
feature can be made in a separate patch.
To put the feature to test, replace duplicated code for
Wshadow and Wold-style-cast with the SuppressInSystemMacro tag.
Also disable the warning for C++20 designators, fixing #52944.

"driver <flags> -- <input>" is a particularly convenient form of the
compile command to manipulate, with fewer special cases to handle.
Guaranteeing that the output command is of that form is cheap and makes
it easier to consume the result in some cases.

A function call `unresolved()` in C will generate an implicit declaration
of the missing function and warn `ext_implicit_function_decl` or so.
(Compared to in C++ where we get `err_undeclared_var_use`).
We want to try to resolve these names.
Unfortunately typo correction is disabled in sema for performance
reasons unless this warning is promoted to error.
(We need typo correction for include-fixer.)
It's not clear to me where a switch to force this correction on should
go, include-fixer is kind of a hack. So hack more by telling sema we're
promoting them to error.

depending on config we'll return partial or no responses.
We try to avoid doing the analysis for hints we're not going to return.

This means it's a "real feature" in clangd 14, albeit one that requires special
client support.
- remove "preview" from the flag description
- expose the `clangdInlayHints` capability by default
- provide `position` as well as `range`
- support `InlayHintsParams.range` to restrict the range retrieved
- inlay hint list is in document order (sorted by position)
Still to come: control feature via config rather than flag.
