Matt Arsenault 1349a04ef5 AMDGPU: Make v2i16/v2f16 legal on VI 
This usually results in better code. Fixes using
inline asm with short2, and also fixes having a different
ABI for function parameters between VI and gfx9.

Partially cleans up the mess used for lowering of the d16
operations. Making v4f16 legal will help clean this up more,
but this requires additional work.
