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/mips/mips.md (*udivmod<mode>4, udivmod<mode>4_mips16): Fix
	split condition.
