AMDGPU: Assume f32 denormals are enabled by default

Browse Source 
This will likely introduce catastrophic performance regressions on
older subtargets, but should be correct. A follow up change will
remove the old fp32-denormals subtarget features, and switch to using
the new denormal-fp-math/denormal-fp-math-f32 attributes. Frontends
should be making sure to add the denormal-fp-math-f32 attribute when
appropriate to avoid performance regressions.

Changes to the AMDGPU Target
-----------------------------
* The backend default denormal handling mode has been switched to on
for all targets for all compute function types. Frontends wishing to
retain the old behavior should explicitly request f32 denormal
flushing.
Changes to the AVR Target
