aco: don't constant-propagate into subdword PSEUDO instructions

PSEUDO instructions are lowered using SDWA, and thus,
cannot take literals and before GFX9 cannot take constants
at all. As the in-register representation differs between
32bit and 16bit floats, we first need to ensure correct
behavior.
