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 f43c2a0b49 AMDGPU: Insert moves of frame index to value operands 
Strengthen tests of storing frame indices.

Right now this just creates irrelevant scheduling changes.

We don't want to have multiple frame index operands
on an instruction. There seem to be various assumptions
that at least the same frame index will not appear twice
in the LocalStackSlotAllocation pass.

There's no reason to have this happen, and it just
makes it easy to introduce bugs where the immediate
offset is appplied to the storing instruction when it should
really be applied to the value being stored as a separate
add.

This might not be sufficient. It might still be problematic
to have an add fi, fi situation, but that's even less unlikely
to happen in real code.

Matt Arsenault 7227cc1a48 AMDGPU: Don't try to use LDS/vector for private if pointer value stored 
If the pointer is the store's value operand, this would produce
a broken module. Make sure the use is actually for the pointer operand.
