Summary:
The macro `INSTANTIATE_TEST_CASE_P` is defined as
```
\# define INSTANTIATE_TEST_CASE_P(prefix, test_case_name, generator, ...) \
...
```
If we build the test case with -werror, we will get an error like
```
error: ISO C++11 requires at least one argument for the "..." in a
variadic macro
testing::ValuesIn(TestClangConfig::allConfigs()));
^
```
This patch fixes that.

Summary:
The syntax tree test uses a helper function that executes all testing
assertions. When an assertion fails, the only line number that gets
printed to the log refers to the helper function. After this change, we
would also get the line number of the EXPECT_TRUE macro invocation
(unfortunately, the line number of the last token of it, not the first
one, but there's not much I can do about it).

Summary:
I think we would be better off with tests explicitly specifying the
language mode. Right now Lang_C means C99, but reads as "any C version",
or as "unspecified C version".
I also changed '-std=c++98' to '-std=c++03' because they are aliases (so
there is no difference in practice), because Clang implements C++03
rules in practice, and because 03 makes a nice sortable progression
between 03, 11, 14, 17, 20.

`RewriteRule`'s `applyFirst` was brittle with respect to the default setting of the

Summary:
Currently, all changes returned by a single application of a rule must fit in
one atomic change and therefore must apply to one file. However, there are
patterns in which a single rule will want to modify multiple files; for example,
a header and implementation to change a declaration and its definition. This
patch relaxes Transformer, libTooling's interpreter of RewriteRules, to support
multiple changes.

This reverts commit 97aa593a83 as it
causes problems (PR45453) https://reviews.llvm.org/D77574#1966321.
This additionally adds an explicit reference to FrontendOpenMP to
clang-tidy where ASTMatchers is used.
This is hopefully just a temporary solution. The dependence on
`FrontendOpenMP` from `ASTMatchers` should be handled by CMake
implicitly, not us explicitly.

Move the listing of allowed clauses per OpenMP directive to the new
macro file in `llvm/Frontend/OpenMP`. Also, use a single generic macro
that specifies the directive and one allowed clause explicitly instead
of a dedicated macro per directive.
We save 800 loc and boilerplate for all new directives/clauses with no
functional change. We also need to include the macro file only once and
not once per directive.
Depends on D77112.

Summary:
This patch removes delayed folding and replaces it with forward peeking.
Delayed folding was previously used as a solution to the problem that
declaration doesn't have a representation in the AST. For example following
code:
```
int a,b;
```
is expressed in the AST as:
```
TranslationUnitDecl
|-...
|-VarDecl `int a`
`-VarDecl `int b`
```
And in the syntax tree we need:
```
*: TranslationUnit
`-SimpleDeclaration
|-int
|-SimpleDeclarator
| `-a
|-,
|-SimpleDeclarator
| `-b
|-;
```
So in words, we need to create SimpleDeclaration to be a parent of
SimpleDeclarator nodes. Previously we used delayed folding to make sure SimpleDeclarations will be
eventually created. And in case multiple declarators requested declaration
creation, declaration range was extended to cover all declarators.
This design started to be hard to reason about, so we decided to replace it with
forward peeking. The last declarator node in the chain is responsible for creating
SimpleDeclaration for the whole chain. Range of the declaration corresponds to
the source range of the declarator node. Declarator decides whether its the last
one by peeking to the next AST node (see `isResponsibleForCreatingDeclaration`).
This patch does following:
* Removed delayed folding logic
* Tweaks Token.dumpForTests
* Moves getQualifiedNameStart inside BuildTreeVisitor
* Extracts BuildTreeVisitor.ProcessDeclaratorAndDeclaration
* Renames Builder.getDeclRange to Builder.getDeclarationRange and uses the
method in all places.
* Adds a bunch of tests

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
Summary: Currently, an attempt to rewrite source code inside a macro expansion succeeds, but results in empty text, rather than failing with an error. This patch restructures to the code to explicitly validate ranges before attempting to edit them.
