[PATCH] D39204: [CodeGen] __builtin_sqrt should map to the compiler's intrinsic sqrt function

Working my way through the stack: does the sqrt LangRef change mean we can revert https://reviews.llvm.org/rL265521? What allows us to transform any of those libm calls that set errno to vectors in the first place?

I'm even more confused than usual, but if I can find a way to untangle this mess, I'll try to start making patches.
