[SystemZ] Move sign_extend optimization to PerformDAGCombine
The target was marking SIGN_EXTEND as Custom because it wanted to optimize
certain sign-extended shifts. In all other respects the extension is Legal,
so it'd be better to do the optimization in PerformDAGCombine instead.
No functional change intended.
