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/s390/s390.md (*cstorecc<mode>_z13): Fix split condition.
* config/s390/vector.md (fprx2_to_tf, tf_to_fprx2): Likewise.
