Yingwei Zheng f066d7504e [Reland][SCEV] teach isImpliedViaOperations about samesign (#133711) 
This patch relands https://github.com/llvm/llvm-project/pull/124270.
Closes https://github.com/llvm/llvm-project/issues/126409.

The root cause is that we incorrectly preserve the samesign flag after
truncating operands of an icmp:
