Using needs_vop3 check was flawed because it would only combine the
literal if the first operand is the literal. If the second or third
operand is the literal, then needs_vop3 will be true and the literal will
not be combined.

We could create VALU instructions which read two sgprs, but only if isel
created an instruction which already read one of them.
This change is in a separate patch from the apply_sgprs() rewrite so that
it can be tested if the rewrite affected anything.

Right now, it's implemented as a no-op for everyone. For most drivers,
it's a switch case in the NIR -> whatever which just breaks. For ir3,
they already have code to delete tessellation barriers so we just add a
case to also delete memory_barrier_tcs_patch.
