Craig Topper f668a08e00 [DAGCombiner][RISCV] Optimize (zext nneg (truncate X)) if X has known sign bits. (#82227) ...

This treats the zext nneg as sext if X is known to have sufficient sign
bits to allow the zext or truncate or both to removed. This code is
taken from the same optimization for sext.
