[AMDGPU] Supress unused sdwa insts generation

[rampitec]

Summary

Do not generate non-existing sdwa instructions. It reduces the
number of generated instructions by 175.

[rampitec]

Added VOPC. This has erased 175 instructions in total.

[nhaehnle]

I haven't looked into the set of instructions that are effected by this, but the TableGen LGTM.

Most of the shaved instructions are v_cmpx.

[vpykhtin]

LGTM.
