Kostya Kortchinsky 988fab3f66 [sanitizer] Split coverage into separate RT in sanitizer_common ... Summary: `sanitizer_common`'s coverage support is fairly well separated, and libcdep by default. Several sanitizers don't make use of coverage, and as far as I can tell do no benefit from the extra dependencies pulled in by the coverage public interface functions. The following sanitizers call `InitializeCoverage` explicitely: MSan, ASan, LSan, HWAsan, UBSan. On top of this, any sanitizer bundling RTUBSan should add the coverage RT as well: ASan, Scudo, UBSan, CFI (diag), TSan, MSan, HWAsan. So in the end the following have no need: DFSan, ESan, CFI, SafeStack (nolibc anyway), XRay, and the upcoming Scudo minimal runtime. I tested this with all the sanitizers check-* with gcc & clang, and in standalone on Linux & Android, and there was no issue. I couldn't test this on Mac, Fuchsia, BSDs, & Windows for lack of an environment, so adding a bunch of people for additional scrunity. I couldn't test HWAsan either.
