AMDGPU: Change ABI of 16-bit element vectors on gfx6/7 (#175781) 
Fix ABI on old subtargets so match new subtargets, packing
16-bit element subvectors into 32-bit registers. Previously
this would be scalarized and promoted to i32/float.

Note this only changes the vector cases. Scalar i16/half are
still promoted to i32/float for now. I've unsuccessfully tried
to make that switch in the past, so leave that for later.

This will help with removal of softPromoteHalfType.
