Make codegen emit correctly rounded sqrt by default. Emit the fast but only kind of fast expansion in AMDGPUCodeGenPrepare based on !fpmath, like the fdiv case. Hack around visitation ordering problems from AMDGPUCodeGenPrepare using forward iteration instead of a well behaved combiner. https://reviews.llvm.org/D158129
