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/csky/csky.md (*cskyv2_adddi3, *ck801_adddi3, *cskyv2_adddi1_1,
	*cskyv2_subdi3, *ck801_subdi3, *cskyv2_subdi1_1, cskyv2_addcc,
	cskyv2_addcc_invert, *cskyv2_anddi3, *ck801_anddi3, *cskyv2_iordi3,
	*ck801_iordi3, *cskyv2_xordi3, *ck801_xordi3,): Fix split condition.
