Matt Arsenault 3c5e4237c6 AMDGPU: Make some packed shuffles free 
VOP3P instructions can encode access to either
half of the register.

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 59767cea79 AMDGPU: TTI: Make insertelement free.
