r12-6103-g1a7ce8570997eb combines vpcmpuw + zero_extend to vpcmpuw
with the pre_reload splitter, but the splitter transforms the
zero_extend into a subreg which make reload think the upper part is
garbage, it's not correct.
The patch adjusts the zero_extend define_insn_and_split to
define_insn to keep zero_extend.
