[PATCH] D23531: [Darwin] Stop linking libclang_rt.eprintf.a

The eprintf library was added before the general OS X builtins library existed as a place to store one builtin function. Since we have for several years had an actual mandated builtin library for OS X > 10.5, we should just merge eprintf into the main library.

This change will resolve PR28855.

As a follow up I'll also patch compiler-rt to not generate the eprintf library anymore.
