We add the method `SyntaxTreeTest::treeDumpEqualOnAnnotations`, which
allows us to compare the treeDump of only annotated code. This will reduce a
lot of noise from our `BuildTreeTest` and make them short and easier to
read.
We do that because:
* Big tests generated big tree dumps that could hardly serve as documentation.
* In most cases the tests didn't share setup, thus there was not much addition in lines of code.
We split tests for:
* `UserDefinedLiteral`
* `NestedBinaryOperator`
* `UserDefinedBinaryOperator`
* `UserDefinedPrefixOperator`
* `QualifiedId`

For an user define `<`, `x < y` would yield the syntax tree:
```
BinaryOperatorExpression
|-IdExpression
| `-UnqualifiedId
| `-x
|-IdExpression
| `-UnqualifiedId
| `-<
`-IdExpression
`-UnqualifiedId
`-y
```
But there is no syntatic difference at call site between call site or
built-in `<`. As such they should generate the same syntax tree, namely:
```
BinaryOperatorExpression
|-IdExpression
| `-UnqualifiedId
| `-x
|-<
`-IdExpression
`-UnqualifiedId
`-y
```

Currently, changes to includes are applied to an entire rule. However,
include changes may be specific to particular edits within a rule (for example,
they may apply to one file but not another). Also, include changes may need to
carry metadata, just like other changes. So, we make include changes first-class
edits.

Use spaces to align binary and ternary expressions when using AlignOperands and UT_AlignWithSpaces.
This fixes an oversight in the new UT_AlignWithSpaces option (see D75034), which did not correctly identify the alignment of binary/ternary expressions.

Summary:
We want NestedNameSpecifier syntax nodes to be generally supported, not
only for `DeclRefExpr` and `DependentScopedDeclRefExpr`.
To achieve this we:
* Use the `RecursiveASTVisitor`'s API to traverse
`NestedNameSpecifierLoc`s and automatically create its syntax nodes
* Add links from the `NestedNameSpecifierLoc`s to their syntax nodes.
In this way, from any semantic construct that has a `NestedNameSpecifier`,
we implicitly generate its syntax node via RAV and we can easily access
this syntax node via the links we added.
On the frontend side, this patch recovers AIX static init implementation to
use the linkage type and function names Clang chooses for sinit related function.
On the backend side, this patch sets correct linkage and function names on aliases
created for sinit/sterm functions.

This is our grammar rule for nested-name-specifiers:
globalbal-specifier:
/*empty*/
simple-template-specifier:
template_opt simple-template-id
name-specifier:
global-specifier
decltype-specifier
identifier
simple-template-specifier
nested-name-specifier:
list(name-specifier, ::, non-empty, terminated)
It is a relaxed version of C++ [expr.prim.id] and quite simpler to map to our API.
TODO: refine name specifiers, `simple-template-name-specifier` and
decltype-name-specifier` are token soup for now.
Summary:
The MultiLine option in BreakBeforeBraces was only handling standard
control statement, leading to invalid indentation with for each macros:
Previous behavior:
/* invalid: brace should be on the same line */
Q_FOREACH(int a; list)
{
foo();
}
/* valid */
Q_FOREACH(int longVariable;
list)
{
foo();
}
To fix this, simply add the TT_ForEachMacro kind in the list of
recognized control statements for the multiline option.
This is a fix for https://bugs.llvm.org/show_bug.cgi?id=44632

NamedDecl::printName will print the pretty-printed name of the entity, which
is not what we want here (we should print "enum { e };" instead of "enum
(unnamed enum at input.cc:1:5) { e };").
For now only DecompositionDecl and MDGuidDecl have an overloaded printName so
this does not result in any functional change, but this change is needed since
I will be adding overloads to better handle unnamed entities in diagnostics.
This was the last binary operator that we supported but didn't have any
test coverage. The recent fix in a crash in member pointers allowed us
to add this test.

The logic was using incorrect flag versions. For example:
- `-target=` can't be a prefix, it must be `--target=`.
- `--driver-mode` can't appear on its own, value must be attached to it.
While fixing those, also changes the append logic to make use of new
`--target=X` format instead of the legacy `-target X` version.
In addition to that makes use of the OPTTable instead of hardcoded strings to
make sure helper also gets updated if clang's options are modified.

It turned out that the D78704 included a private LLVM header, which is excluded
from the LLVM install target.
I'm substituting that `#include` with the public one by moving the necessary
`#define` into that. There was a discussion about this at D78704 and on the
cfe-dev mailing list.
I'm also placing a note to remind others of this pitfall.

This cleans up several CMakeLists.txt's where -Wno-suggest-override was manually specified. These test targets now inherit this flag from the gtest target.
Some unittests CMakeLists.txt's, in particular Flang and LLDB, are not touched by this patch. Flang manually adds the gtest sources itself in some configurations, rather than linking to LLVM's gtest target, so this fix would be insufficient to cover those cases. Similarly, LLDB has subdirectories that manually add the gtest headers to their include path without linking to the gtest target, so those subdirectories still need -Wno-suggest-override to be manually specified to compile without warnings.

This patch adds various combinators that help in constructing `EditGenerator`s:
* `noEdits`
* `ifBound`, specialized to `ASTEdit`
* `flatten` and `flattenVector` which allow for easy construction from a set
of sub edits.
* `shrinkTo`, which generates edits to shrink a given range to another that
it encloses.

add_compile_options is more sensitive to its location in the file than add_definitions--it only takes effect for sources that are added after it. This updated patch ensures that the add_compile_options is done before adding any source files that depend on it.
Using add_definitions caused the flag to be passed to rc.exe on Windows and thus broke Windows builds.
After lots of follow-up fixes, there are still problems, such as
-Wno-suggest-override getting passed to the Windows Resource Compiler
because it was added with add_definitions in the CMake file.
Rather than piling on another fix, let's revert so this can be re-landed

If there is no record in compile_commands.json, we try to find suitable record with `MatchTrie.findEquivalent()` call.
This is very expensive operation with a lot of `llvm::sys::fs::equivalent()` calls in some cases.
This patch disables file symlinks for performance reasons.
Example scenario without this patch:
- compile_commands.json generated at clangd build (contains ~3000 files).
- it tooks more than 1 second to get compile command for newly created file in the root folder of LLVM project.
- we wait for 1 second every time when clangd requests compile command for this file (at file change).
