`TargetOpts->Triple` is initialized as llvm::sys::getDefaultTargetTriple() which may not be normalized.
If LLVM_DEFAULT_TARGET_TRIPLE is powerpc64le-linux-gnu, we should check
check `-triple powerpc64le-linux-gnu`, instead of (normalized) `-triple powerpc64le-unknown-linux-gnu`
This change includes the following:
- Add additional information in the relevant table-gen files to encode
the necessary information to automatically parse the argument into a
CompilerInvocation instance and to generate the appropriate command
line argument from a CompilerInvocation instance.
- Extend OptParserEmitter to emit the necessary macro tables as well as
constant tables to support parsing and generating command line
arguments for options that provide the necessary information.
- Port some options to use this new system for parsing and generating
command line arguments.

Summary:
After D50078, we're experiencing unexpected un-indent using a style combining `AlignOperands: DontAlign` with `BreakBeforeTernaryOperators: false`, such as Google's JavaScript style:
```
% bin/clang-format -style=google ~/test.js
aaaaaaaaaaa = bbbbbbbb ? cccccccccccccccccc() :
dddddddddd ? eeeeeeeeeeeeee :
fffff;
```
The issue lies with the interaction of `AlignOperands: DontAlign` and the edited code section in ContinuationIndenter.cpp, which de-dents the intent by `Style.ContinuationIndentWidth`. From [[ ac3e5c4d93/clang/include/clang/Format/Format.h (L170) | the documentation ]] of AlignOperands: DontAlign:
> The wrapped lines are indented `ContinuationIndentWidth` spaces from the start of the line.
So the de-dent effectively erases the necessary `ContinuationIndentWidth` in that case.
This patch restores the `AlignOperands: DontAlign` behavior, producing:
```
% bin/clang-format -style=google ~/test.js
aaaaaaaaaaa = bbbbbbbb ? cccccccccccccccccc() :
dddddddddd ? eeeeeeeeeeeeee :
fffff;
```

outer levels as retained rather than omitting their arguments.
This better reflects what's going on (we're performing a substitution
while still inside a template), and in theory is more correct, but I've
not found a testcase where it matters in practice (largely because we
don't allow alias templates to be declared inside a function).
Fixed AST dumping of SubstNonTypeTemplateParm[Pack]Expr to demonstrate
that we're properly substituting through dependent alias templates. (We
can't deduce properly through these yet, but we can at least produce the
right input to template argument deduction.)
No functionality change intended.
Currently, using the nullPointerConstant AST matcher can lead to
assertions in situations where a node to be matched does not have a
valid type associated with it, such as a ParenListExpr. This patch
addresses that by saying such nodes cannot be a null pointer constant.
This addresses PR46353.
Summary:
In ASTMatcher, when we have `has(...)` and `hasParent(...)` called with the same internal matcher on the same node, the memoization process will mix-up the two calls because the direction of the traversal is not part of the memoization key.
This patch adds this information.

Summary:
Currently, `cat` validates range selections before extracting the corresponding
source text. However, this means that any range inside a macro is rejected as an
error. This patch changes the implementation to first try to map the range to
something reasonable. This makes the behavior consistent with handling of ranges
used for selecting portions of the source to edit.
Also updates a clang-tidy lit-test for one of the checks which was affected by
this change.

Summary:
This patch fixes bug #44192
When clang-format is run with option AllowShortBlocksOnASingleLine, it is expected to either succeed in putting the short block with its control statement on a single line or fail and leave the block as is. When brace wrapping after control statement is activated, if the block + the control statement length is superior to column limit but the block alone is not, clang-format puts the block in two lines: one for the control statement and one for the block. This patch removes this unexpected behaviour. Current unittests are updated to check for this behaviour.

Checker dependencies were added D54438 to solve a bug where the checker names
were incorrectly registered, for example, InnerPointerChecker would incorrectly
emit diagnostics under the name MallocChecker, or vice versa [1]. Since the
system over the course of about a year matured, our expectations of what a role
of a dependency and a dependent checker should be crystallized a bit more --
D77474 and its summary, as well as a variety of patches in the stack
demonstrates how we try to keep dependencies to play a purely modeling role. In
fact, D78126 outright forbids diagnostics under a dependency checkers name.
These dependencies ensured the registration order and enabling only when all
dependencies are satisfied. This was a very "strong" contract however, that
doesn't fit the dependency added in D79420. As its summary suggests, this
relation is directly in between diagnostics, not modeling -- we'd prefer a more
specific warning over a general one.
To support this, I added a new dependency kind, weak dependencies. These are not
as strict of a contract, they only express a preference in registration order.
If a weak dependency isn't satisfied, the checker may still be enabled, but if
it is, checker registration, and transitively, checker callback evaluation order
is ensured.
If you are not familiar with the TableGen changes, a rather short description
can be found in the summary of D75360. A lengthier one is in D58065.

Retrieving the parameter location of functions was disabled because it
may causes crashes due to the fact that functions may have multiple
declarations and without definition it is difficult to ensure that
always the same declration is used. Now parameters are stored in
`ParamRegions` which are independent of the declaration of the function,
therefore the same parameters always have the same regions,
independently of the function declaration used actually. This allows us
to remove the limitation described above.
Differential Revision: https://reviews.llvm.org/D80286
Currently, parameters of functions without their definition present cannot
be represented as regions because it would be difficult to ensure that the
same declaration is used in every case. To overcome this, we split
`VarRegion` to two subclasses: `NonParamVarRegion` and `ParamVarRegion`.
The latter does not store the `Decl` of the parameter variable. Instead it
stores the index of the parameter which enables retrieving the actual
`Decl` every time using the function declaration of the stack frame. To
achieve this we also removed storing of `Decl` from `DeclRegion` and made
`getDecl()` pure virtual. The individual `Decl`s are stored in the
appropriate subclasses, such as `FieldRegion`, `ObjCIvarRegion` and the
newly introduced `NonParamVarRegion`.

We previously took a shortcut by assuming that if a subobject had a

always invoke it, and could avoid going through overload resolution.

also won't be the case for copy-assignments with requires-clauses
