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.

README.txt
AddressSanitizer RT
================================
This directory contains sources of the AddressSanitizer (ASan) runtime library.
Directory structure:
README.txt : This file.
Makefile.mk : File for make-based build.
CMakeLists.txt : File for cmake-based build.
asan_*.{cc,h} : Sources of the asan runtime library.
scripts/* : Helper scripts.
tests/* : ASan unit tests.
Also ASan runtime needs the following libraries:
lib/interception/ : Machinery used to intercept function calls.
lib/sanitizer_common/ : Code shared between various sanitizers.
ASan runtime currently also embeds part of LeakSanitizer runtime for
leak detection (lib/lsan/lsan_common.{cc,h}).
ASan runtime can only be built by CMake. You can run ASan tests
from the root of your CMake build tree:
make check-asan
