AMDGPU: Avoid creating vector extracts if we aren't going to do anything

Try to avoid expensive checks failures from reporting no changes
when some dead instructions were introduced.

AMDGPU: Correctly lower llvm.sqrt.f32

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.
