But I'm not sure where to disable it. HWASan has [hwasan_platform_interceptors.h](https://github.com/llvm/llvm-project/blob/main/compiler-rt/lib/hwasan/hwasan_platform_interceptors.h), where lots of interceptors are disabled, but I can't find an equivalent place for ASan.

They need to  be moved from sanitizer_common into msan_iterceptors
