AMDGPU: Change ABI of 16-bit scalar values for gfx6/gfx7 (#175795) 
Keep bf16/f16 values encoded as the low half of a 32-bit register,
instead of promoting to float. This avoids unwanted FP effects
from the fpext/fptrunc which should not be implied by just
passing an argument. This also fixes ABI divergence between
SelectionDAG and GlobalISel.

I've wanted to make this change for ages, and failed the last
few times. The main complication was the hack to return
shader integer types in SGPRs, which now needs to inspect
the underlying IR type.
