Younan Zhang 5b4513afa4 [clang][clangd] Ensure the stack bottom before building AST
`clang::runWithSufficientStackSpace` requires the address of the
initial stack bottom to prevent potential stack overflows.

In addition, add a fallback to ASTFrontendAction in case any client
forgets to call it when not through CompilerInstance::ExecuteAction,
which is rare.

Fixes https://github.com/clangd/clangd/issues/1745.

Welcome to the repository of extra Clang Tools.  This repository holds tools
that are developed as part of the LLVM compiler infrastructure project and the
Clang frontend.  These tools are kept in a separate "extra" repository to
allow lighter weight checkouts of the core Clang codebase.

All discussion regarding Clang, Clang-based tools, and code in this repository
should be held using the standard Clang forum:
  https://discourse.llvm.org/c/clang

Code review for this tree should take place on the standard Clang patch and
commit lists:
  http://lists.llvm.org/mailman/listinfo/cfe-commits

If you find a bug in these tools, please file it in the LLVM bug tracker:
