[SCEV] Teach SCEVExpander to use zext nneg when possible (#70815) zext nneg was recently added to the IR in #67982. Teaching SCEVExpander to emit nneg when possible is valuable since SCEV may have proved non-trivial facts about loop bounds which would otherwise be lost when materializing the value.
