[PATCH] D40594: [InstCombine] miscompile of __builtin_fmod

Side note: I think there is a different bug here in clang because from what I can tell, we convert the builtin or libcall to 'frem' even when errno could be set by the call. https://reviews.llvm.org/D40044 doesn't address this case because frem is an LLVM instruction rather than an LLVM intrinsic.
