This is a follow-up to the rL335185. Those commit adds some WrapperPat patterns for microMIPS target. But declaration of the WrapperPat class is under the NotInMicroMips predicate and microMIPS patterns cannot be selected because predicate (Subtarget->inMicroMipsMode()) && (!Subtarget->inMicroMipsMode()) is always false. This change move out the WrapperPat class declaration from the NotInMicroMips predicate and enables microMIPS WrapperPat patterns.
