Matt Arsenault e3862cdc93 AMDGPU: Use rcp for fdiv 1, x with fpmath metadata 
Using rcp should be OK for safe math usually, so this
should not be replacing the original fdiv.

Matt Arsenault a1fe17c9ad 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.
