  AMDGPU/GlobalISel: Fix some illegal scalar argument types

Fixes integers that don't evenly divide to i32 pieces. We should
probably extract some of the code in the legalizer to start handling
argument breakdowns. I'm dissatisfied with the argument lowering's
handling of vectors for example, and we should not be producing the
weird G_EXTRACTs we do now.
