I fixed a small bug in the C2 compiler.
It appeared in our s390/zArch port running hs25.31 with jdk6 when executing

Split_if encounters a ConstraintCast without region edge, which is a valid pattern.
But it reads the region edge unconditionally, thus failing.

Please review this change.  I please need a sponsor.

Best regards,
