    M llvm/lib/Transforms/Instrumentation/MemorySanitizer.cpp

  Log Message:
  -----------
  [msan] Add support for disable_sanitizer_instrumentation attribute

Unlike __attribute__((no_sanitize("memory"))), this one will cause MSan
to skip the entire function during instrumentation.

Depends on https://reviews.llvm.org/D108029
