[PATCH] D82926: [libfuzzer] [clang] Add __has_feature(fuzzing_coverage)

[Mitch Phillips via Phabricator via cfe-commits]

hctim added a comment.

So - the `FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION` flag is a property of the build system and not that of the compiler. There are some places (android) where enabling `FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION` globally changes the behaviour of large amounts of libraries in ways that break the build system.

Having this flag allows us to make targeted compile-time changes to libc based on sancov that don't require enabling `FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION` across the entire build system.
