  This patch is to fix some non-robust split conditions in some
define_insn_and_splits, to make each of them applied on top of
the corresponding condition for define_insn part, otherwise the
splitting could perform unexpectedly.

gcc/ChangeLog:

	* config/m32c/cond.md (stzx_reversed_<mode>, movhicc_<code>_<mode>):
	Fix split condition.
