NFC: Clean up of IntrusiveRefCntPtr construction from raw pointers. (#151545)
Handles clang::DiagnosticsEngine and clang::DiagnosticIDs.

For DiagnosticIDs, this mostly migrates from `new DiagnosticIDs` to
convenience method `DiagnosticIDs::create()`.

[clang] Remove intrusive reference count from DiagnosticOptions (#139584)
The `DiagnosticOptions` class is currently intrusively
reference-counted, which makes reasoning about its lifetime very
difficult in some cases. For example, `CompilerInvocation` owns the
`DiagnosticOptions` instance (wrapped in `llvm::IntrusiveRefCntPtr`) and
only exposes an accessor returning `DiagnosticOptions &`. One would
think this gives `CompilerInvocation` exclusive ownership of the object,
but that's not the case:

```c++
void shareOwnership(CompilerInvocation &CI) {
  llvm::IntrusiveRefCntPtr<DiagnosticOptions> CoOwner = &CI.getDiagnosticOptions();
  // ...
}
```

This is a perfectly valid pattern that is being actually used in the
codebase.

I would like to ensure the ownership of `DiagnosticOptions` by
`CompilerInvocation` is guaranteed to be exclusive. This can be
leveraged for a copy-on-write optimization later on. This PR changes
usages of `DiagnosticOptions` across `clang`, `clang-tools-extra` and
`lldb` to not be intrusively reference-counted.

[clang][frontend] Require invocation to construct CompilerInstance (#137668)
This PR makes it so that `CompilerInvocation` needs to be provided to
`CompilerInstance` on construction. There are a couple of benefits in my
view:
* Making it impossible to mis-use some `CompilerInstance` APIs. For
example there are cases, where `createDiagnostics()` was called before
`setInvocation()`, causing the `DiagnosticEngine` to use the
default-constructed `DiagnosticOptions` instead of the intended ones.
* This shrinks `CompilerInstance`'s state space.
* This makes it possible to access **the** invocation in
`CompilerInstance`'s constructor (to be used in a follow-up).

[clang][test] add TestLanguage.def to specify all tested language versions (#94243)
Adds a def file to have a single location where tested language versions
are specified. Removes the need to update multiple locations in the
testing infrastructure to add a new language version to be tested. Test
instatiation can now include all languages without needing to specify
them.
This patch also adds pretty printing for instantiated test names. That
means, that a test instantiated with C++23 will have the name
`...TestSuite/TestName/CXX23` instead ending with some number (index of
the argument for instantiation of the test), which provides a better
experience when encountering a test failure with a specific language
version. The suffix will also contain an `_win` if the target contains
`win`.

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.

263dcf452f [syntax] Introduce a TokenManager interface.
TokenManager defines Token interfaces for the clang syntax-tree. This is the level
of abstraction that the syntax-tree should use to operate on Tokens.

It decouples the syntax-tree from a particular token implementation (TokenBuffer
previously).  This enables us to use a different underlying token implementation
for the syntax Leaf node -- in clang pseudoparser, we want to produce a
syntax-tree with its own pseudo::Token rather than syntax::Token.

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`
