Shivanshu Goyal 2168dbf4cc getClangStripDependencyFileAdjuster(): Do not remove -M args when using MSVC cl driver
MSVC's cl.exe has a few command line arguments which start with -M such
as "-MD", "-MDd", "-MT", "-MTd", "-MP".
These arguments are not dependency file generation related, and these
arguments were being removed by getClangStripDependencyFileAdjuster()
which was wrong.

Eduardo Caldas c655d80815 [SyntaxTree] Extend the syntax tree dump to also cover `NodeRole`
We should see `NodeRole` information in the dump because that exposes how the
accessors will behave.

Functional changes in the dump:
* Surround Leaf tokens with `'`
* Append `Node` dumps with `NodeRole` information, except for unknown roles
* Append marks to `Node` dumps, instead of prepending

Non-functional changes:
* `::dumpTokens(llvm::raw_ostream, ArrayRef<syntax::Token>, const
SourceManager &SM)` always received as parameter a `syntax::Token *`
pointing to `Leaf::token()`. Changed the function to
`dumpLeaf(llvm::raw_ostream, syntax::Leaf *, const SourceManager&)`
* `dumpTree` acted on a Node, rename to `dumpNode`

Yitzhak Mandelbaum d8c1f43dcc [libTooling] Move RewriteRule include edits to ASTEdit granularity.
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.

Yitzhak Mandelbaum 645dd1b3bf [libTooling] Cleanup and reorder `RewriteRule.h`.
This patch lifts `RootID` out of the `RewriteRule` class so that constructs
(e.g. inline functions) can that refer to the root id don't need to depend on
the `RewriteRule` class.

With this dependency, the patch is able to collect all `ASTEdit` helper function
declarations together with the class declaration, before the introduction of the
`RewriteRule` class. In the process, we also adjust some of the comments.

This patch is essentially a NFC.

Eduardo Caldas f9500cc487 [SyntaxTree] Expand support for `NestedNameSpecifier`
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.

This is our grammar rule for nested-name-specifiers:

  template_opt simple-template-id
name-specifier:
  global-specifier
  decltype-specifier
  identifier

[clang][nearly-NFC] Remove some superfluous uses of NamedDecl::getNameAsString
`OS << ND->getDeclName();` is equivalent to `OS << ND->getNameAsString();`

This is not quite a NFC since two uses of `getNameAsString` in a

[clang][Tooling] Fix addTargetAndModeForProgramName to use correct flag names
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.

Summary:
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).
