[Reland][Clang][CodeGen][UBSan] Add more precise attributes to recoverable ubsan handlers (#135135)
This patch relands https://github.com/llvm/llvm-project/pull/130990.
If the check value is passed by reference, add `memory(read)`.
Original PR description:
This patch adds `memory(argmem: read, inaccessiblemem: readwrite)` 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).
