Thanks, asan_abi LGTM.

I don't have good reasons to object that patch, but I suspect it's sub-optimal. 
But we may get a valuable expirience.

We do this for hwasan for Android, and to some extent msan for Chromium. 
@eugenis maybe can share more info.

I guess we just have no way to enforce that. A couple of buildbots with "stable 
clang" + "HEAD runtime" and "HEAD clang" + "stable runtime" which do some

enforce default set of flags.
