nir/gcm: Rework the schedule late loop
This fixes a bug in code motion that occurred when the best block is the
same as the schedule early block. In this case, because we're checking
(lca != def->parent_instr->block) at the top of the loop, we never get to
the check for loop depth so we wouldn't move it out of the loop. This
commit reworks the loop to be a simple for loop up the dominator chain and
we place the (lca != def->parent_instr->block) check at the end of the
loop.
