compiler_rt: fix and simplify additional Windows exports
Simplifies the logic, clarifies the comment, and fixes a minor bug,
which is that we exported the Windows ABI name *instead* of the standard
compiler-rt name, but it's meant to be exported *in addition* to the
standard name (this is LLVM's behavior and it is more useful).
