broadcom/vc5: Remove no-op MOVs after register allocation.

We emit some MOVs to track lifetimes of payload registers, but we don't
need there to be actual MOV instructions for them.

total instructions in shared programs: 101045 -> 100423 (-0.62%)
instructions in affected programs:     37083 -> 36461 (-1.68%)
