Matt Arsenault 1022c0dfde AMDGPU: Decompose all values to 32-bit pieces for calling conventions 
This is the more natural lowering, and presents more opportunities to
reduce 64-bit ops to 32-bit.

This should also help avoid issues graphics shaders have had with
64-bit values, and simplify argument lowering in globalisel.

Some image loads return these, and it's awkward working
around them not being legal.
