Matt Arsenault	63be72069d	AMDGPU: Change fdiv lowering based on !fpmath metadata If 2.5 ulp is acceptable, denormals are not required, and isn't a reciprocal which will already be handled, replace with a faster fdiv.

AMDGPU: Change fdiv lowering based on !fpmath metadata

If 2.5 ulp is acceptable, denormals are not required, and
isn't a reciprocal which will already be handled, replace
with a faster fdiv.

Simplify the lowering tests by using per function
subtarget features.
