[Clang] Increase the default expression nesting limit (#132021)

This iterates on #104717 (which we had to revert)

In a bid to increase our chances of success, we try to avoid blowing up
the stack by

-  Using `runWithSufficientStackSpace` in ParseCompoundStatement
-  Reducing the size of `StmtVector` a bit
-  Reducing the size of `DeclsInGroup` a bit
- Removing a few `ParsedAttributes` from the stacks in places where they
are not strictly necessary. `ParsedAttributes` is a _huge_ object

On a 64 bits system, the following stack size reductions are observed

```
ParseStatementOrDeclarationAfterAttributes:  344 -> 264
ParseStatementOrDeclaration: 520 -> 376
ParseCompoundStatementBody: 1080 -> 1016
ParseDeclaration: 264 -> 120
```

Fixes #94728

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

Getting in touch

Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
