Jose Maria Casanova Crespo 31c8e14df3 broadcom/compiler: MULTOP in branch delay slots doesn't generate RTOP hazard 
On unconditional branches qpu_set_branch_targets() can fill the delay slots
with a copy of the first instructions of the successor block.

As the qpu validator is sequential it would detect an incorrect hazard
when the MULTOP was copied but the UMUL24 wasn't.

This was identified in debug build when running gfxbench5.aztec_ruins_vk.
