[PATCH] [compiler-rt] Implement AddressSanitizer suppressions

[Alexander Potapenko]

I agree with Alexey.
As we discussed previously, suppressions should not be used to suppress errors in instrumented code (just because it's not possible to recover after calling a noreturn version of __asan_report_error).
Therefore we shouldn't allow "asan_function", and "asan_library" should only ignore reports in the interceptors (I suggest to rename it accordingly).
