Yingwei Zheng 0283bb3afc [Clang][CodeGen][UBSan] Add more precise attributes to recoverable ubsan handlers (#130990) ...

This patch adds `memory(argmem: read, inaccessiblemem: readwrite)
mustprogress` to **recoverable** ubsan handlers in order to unblock some
memory/loop optimizations. It provides an average of 3% performance
improvement on llvm-test-suite (except for 49 test failures due to ubsan
diagnostics).

Closes https://github.com/llvm/llvm-project/issues/130093.
