David Stuttard 3dd28f03d5 [AMDGPU] Ensure trig range reduction only used for subtargets that require it 
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

Matt Arsenault d706d030af 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).

Nicolai Haehnle ea7a0c0467 AMDGPU: Add a shader calling convention 
This makes it possible to distinguish between mesa shaders
and other kernels even in the presence of compute shaders.
