panfrost/midgard: Implement copy propagation

Most copy prop should occur at the NIR level, but we generate a fair
number of moves implicitly ourselves, etc... long story short, it's a
net win to also do simple copy prop + DCE on the MIR. As a bonus, this
fixes the weird imov precision bug once and for good, I think.
