[PATCH] D18513: Simplify isfinite/isnan/isinf in finite-math-only mode

I haven't thought about the behavioral question raised by -ffinite-math-only, but I wanted to know what the code to perform these ops might look like with default settings.

For reference, these bugs are byproducts of that investigation (although not all will be directly applicable to isfinite/isnan/isinf codegen):
