Subject: [PATCH 1/7] [KeyInstr][Clang] Reset atomGroup number for each
function
CGDebugInfo::completeFunction was added previously but mistakenly
not called (dropped through the cracks while putting together
the patch stack). Moved out of #134652 and #134654.

Subject: [PATCH 2/7] [KeyInstr][Clang] For stmt atom
This patch is part of a stack that teaches Clang to generate Key Instructions
metadata for C and C++.
The Key Instructions project is introduced, including a "quick summary" section
at the top which adds context for this PR, here:
https://discourse.llvm.org/t/rfc-improving-is-stmt-placement-for-better-interactive-debugging/82668
The feature is only functional in LLVM if LLVM is built with CMake flag
LLVM_EXPERIMENTAL_KEY_INSTRUCTIONs. Eventually that flag will be removed.
The Clang-side work is demoed here:
https://github.com/llvm/llvm-project/pull/130943
