[Clang] [Tests] Refactor most unit tests to use DynamicRecursiveASTVisitor (#115132)
This pr refactors most tests that use RAV to use DRAV instead; this also
has the nice effect of testing both the RAV and DRAV implementations at
the same time w/o having to duplicate all of our AST visitor tests.

Some tests rely on features that DRAV doesn’t support (mainly post-order
traversal), so those haven’t been migrated. At the same time,
`TestVisitor` is now a DRAV, so I’ve had to introduce a new
`CTRPTestVisitor` for any tests that need to use RAV directly.

[libTooling] Fix getFileRangeForEdit for inner nested template types (#87673)
When there is `>>` in source from the right brackets of a nested
template, the end location of the inner template points into a scratch
space with a single `>` token. This prevents the lexer from seeing the
`>>` token in the original source.

However, this causes the range to appear to be partially in a macro, and
is problematic if we are trying to avoid ranges with any macro
expansions.

This change detects these split tokens in token ranges, converting it to the
corresponding character range without the expansion.

[clang] Prioritze decl comments from macro expansion site (#65481)
For declarations declared inside a macro, e.g.:
```
`#define MAKE_FUNC(suffix) \
         /// Not selected doc comment \
         void func_##suffix(void) {  }

/// Doc comment foo
MAKE_FUNC(foo)

/// Doc comment bar
MAKE_FUNC(bar)
````

Prefer the doc comment at the expansion site instead of the one defined
in the macro.

2307029b1a [libTooling] Rename getRangeForEdit as getFileRangeForEdit
With the addition of `getFileRange`, we rename `getRangeForEdit` as
`getFileRangeForEdit` for consistency in the API.

3432f4bf86 [test] Split out Annotations from TestingSupport
The Annotations helper class does not have a gtest or gmock dependency, but because it's bundled with the rest of TestingSupport, it gets one. By splitting it out, a target can use it without being forced to use LLVM's copy of gtest.

a78d4b5ba7 [libTooling] Add flag to getRangeForEdit to ignore macro expansions
This commit resolves the FIXME around the behavior of
`Lexer::makeFileCharRange` that `getRangeForEdit` inherits around
source locations in macro expansions.

We add a flag to `getRangeForEdit` that allows a caller to disable the
behavior, and instead uses the spelling location instead, with checks
to ensure that the source locations are not within a macro definition.

b78d5380da parse: process GNU and standard attributes on top-level decls
We would previously reject valid input where GNU attributes preceded the
standard attributes on top-level declarations. A previous attribute
handling change had begun rejecting this whilst GCC does honour this
layout. In practice, this breaks use of `extern "C"` attributed
functions which use both standard and GNU attributes as experienced by
the Swift runtime.

Objective-C deserves an honourable mention for requiring some additional
special casing. Because attributes on declarations and definitions
differ in semantics, we need to replicate some of the logic for
detecting attributes to declarations to which they appertain cannot be
attributed. This should match the existing case for the application of
GNU attributes to interfaces, protocols, and implementations.

Take the opportunity to split out the tooling tests into two cases: ones
which process macros and ones which do not.

Special thanks to Aaron Ballman for the many hints and extensive rubber
ducking that was involved in identifying the various places where we
accidentally dropped attributes.

5674a3c880 Fixed a number of typos
I went over the output of the following mess of a command:

(ulimit -m 2000000; ulimit -v 2000000; git ls-files -z |
 parallel --xargs -0 cat | aspell list --mode=none --ignore-case |
 grep -E '^[A-Za-z][a-z]*$' | sort | uniq -c | sort -n |
 grep -vE '.{25}' | aspell pipe -W3 | grep : | cut -d' ' -f2 | less)

and proceeded to spend a few days looking at it to find probable typos
and fixed a few hundred of them in all of the llvm project (note, the
ones I found are not anywhere near all of them, but it seems like a
good start).

6e51991049 [clang][AST] Handle overload callee type in CallExpr::getCallReturnType.
The function did not handle every case. In some cases this
caused assertion failure.
After the fix the function returns DependentTy if the exact
return type can not be determined.

It seems that clang itself does not call the function in the
affected cases but some checker or other code may call it.

ecfa0b2418 [libTooling] Fix maybeExtendRange to support CharRanges.
Currently, `maybeExtendRange` takes a `CharSourceRange`, but only works
correctly for the `TokenRange` case. This change adds proper support for the
`CharRange` case.

38b4516de8 [libTooling] Add function to determine associated text of a declaration.
Summary:
Second attempt -- the first was reverted in commit 0e480b39c66143ad142f9a30d8d40e49d7d7b0ce, because of test breakages. This revision fixes the cause of the test breakages.

Original description follows:
This patch adds `getAssociatedRange` which, for a given decl, computes preceding
and trailing text that would conceptually be associated with the decl by the
reader. This includes comments, whitespace, and separators like ';'.

Summary:
The Transformer library has been growing inside of
lib/Tooling/Refactoring. However, it's not really related to anything else in
that directory. This revision moves all Transformer-related files into their own
include & lib directories.  A followup revision will (temporarily) add
forwarding headers to help any users migrate their code to the new location.

84f2271acd [LibTooling] Add "SourceCode" library for functions relating to source-code manipulation.
Summary:
Introduces a utility library in Refactoring/ to collect routines related to
source-code manipulation.  In this change, we move "extended-range" functions
from the FixIt library (in clangTooling) to this new library.

We need to use this functionality in Refactoring/ and cannot access it if it
resides in Tooling/, because that would cause clangToolingRefactor to depend on
clangTooling, which would be a circular dependency.
