before the first parameter load.
If we did not find all the parameter loads, then we might have
stopped on the head of the block, which could be a CODE_LABEL.
If we inserted before the CODE_LABEL, then we would be putting
the insn in the wrong basic block. In that case, put the insn
after the CODE_LABEL.
