Tim Renouf e30aa6a136 [AMDGPU] Prepare for introduction of v3 and v5 MVTs
AMDGPU would like to have MVTs for v3i32, v3f32, v5i32, v5f32. This
commit does not add them, but makes preparatory changes:

* Fixed assumptions of power-of-2 vector type in kernel arg handling,
  and added v5 kernel arg tests and v3/v5 shader arg tests.

* Added v5 tests for cost analysis.

* Added vec3/vec5 arg test cases.

Some of this patch is from Matt Arsenault, also of AMD.

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).
