Summary:
GFX9 and above support sin/cos instructions with a greater range and thus don't
require a fract instruction prior to invocation.
Added a subtarget feature to reflect this and added code to take advantage of
expanded range on GFX9+
Also updated the tests to check correct behaviour

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).

This makes it possible to distinguish between mesa shaders
and other kernels even in the presence of compute shaders.
