The main motivation is to have ABI-emitting code (in particular for
OpenMP) shared between clang and flang. This structure would require
flang to have a dependency on clang, but conceptually they are
independent frontends.

De facto, every platform has its ABI defined in terms of C therefore
this would effectively required every frontend to depend on clang. I'd
think of the platform ABI to be independent of the parsing
implementation.
