[SystemZ] Bugfix in expandRxSBG() Csmith discovered a program that caused wrong code generation with -O0: When handling a SIGN_EXTEND in expandRxSBG(), RxSBG.BitSize may be less than the Input width (if a truncate was previously traversed), so maskMatters() should be called with a masked based on the width of the sign extend result instead.
