[PATCH] D83154: clang: Add -fcoverage-prefix-map

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

-fdebug-prefix-map does not make sense to me because coverage is not debug info.
I am on the fence whether we need -fcoverage-prefix-map. I created https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96092 (Should --coverage respect -ffile-prefix-map?)

----------------
Drop CC1AsOption

The option does not affect -cc1as (assembly input)
