Richard Sandiford 122a970111 [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.
