I think it makes more sense to have the intrinsics as is, but do the code generation in the X86 target different
depending on some command line flag. For the pattern ISel, this simply amounts to registering the FP_SIN and FP_COS
as nodes which need to be expanded (to calls) if not fast-math is set... What do you think about this approach?

Cool. Here are a couple of requests:
1. I don't think we need an "llvm.abs" intrinsic at the llvm level. This

Hello,
I am trying to make the FP intrinsics (abs, sin, cos, sqrt) I've added
work with the X86ISelPattern, but I'm having some difficulties
understanding what needs to be done. I assume I have to add new
nodetypes for the FP instructions to SelectionDAGNodes.h, and make nodes
for these in SelectionDAGLowering::visitCall when I find the intrinsic...
The part I don't quite
