[PATCH] D97743: Define __GCC_HAVE_DWARF2_CFI_ASM if applicable

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

There are some side effects: because -D is passed as command line options, it has `<command line>` in its filename, so `isWrittenInBuiltinFile` will not match it (`isWrittenInBuiltinFile` can match other built-in macros)...
