Matt Arsenault 3dbeefa978 AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel
Currently the default C calling convention functions are treated
the same as compute kernels. Make this explicit so the default
calling convention can be changed to a non-kernel.

Converted with perl -pi -e 's/define void/define amdgpu_kernel void/'
on the relevant test directories (and undoing in one place that actually
wanted a non-kernel).

Matt Arsenault a8fcfadf46 AMDGPU: Check if users of fneg can fold mods
In multi-use cases this can save a few instructions.

Matt Arsenault 7aad8fd8f4 Enable FeatureFlatForGlobal on Volcanic Islands
This switches to the workaround that HSA defaults to
for the mesa path.

This should be applied to the 4.0 branch.

Matt Arsenault a6867fd441 AMDGPU: Combine fp16/fp64 subtarget features
The same control register controls both, and are set to
the same defaults. Keep the old names around as aliases.

Matt Arsenault e7d8ed32f9 AMDGPU: Swap order of operands in fadd/fsub combine
FMA is canonicalized to constant in the middle operand. Do
the same so fmad matches and avoid an extra combine step.

Matt Arsenault 44e5483ada AMDGPU: Add volatile to test loads and stores
When the memory vectorizer is enabled, these tests break.
These tests don't really care about the memory instructions,
and it's easier to write check lines with the unmerged loads.

Matt Arsenault cabe02e141 Only do fmul (fadd x, x), c combine if the fadd only has one use
This was increasing the instruction count if the fadd has multiple uses.
