[SelectionDAG] Fix for PR30775: Assertion `NodeToMatch->getOpcode() != ISD::DELETED_NODE && "NodeToMatch was removed partway through selection"' failed. NodeToMatch can be modified during matching, but code does not handle this situation. Differential Revision: https://reviews.llvm.org/D29292 llvm-svn: 294003
