Per discussion with @ojhunt and @AaronBallman we are moving towards predefined macros and away from __has_feature and __has_extension for detecting sanitizers and other similar features. The rationale is that __has_feature is only really meant for standardized features (see the comment at the top of clang/include/clang/Basic/Features.def), and __has_extension has the issues discovered as part of #153104. Let's start by defining macros for ASan, HWASan and TSan, consistently with gcc.
