Nikita Popov efe4e7a026 [SCEV] Fix incorrect nsw inference for multiply of addrec (#66500) 
SCEV currently preserves the nsw flag when performing an nsw multiply of
an nsw addrec. While this is legal for nuw, this is not generally the
case for nsw.

This is because nsw mul does not distribute over nsw add:
https://alive2.llvm.org/ce/z/mergCt

Instead, we need either both nuw and nsw to be set
(https://alive2.llvm.org/ce/z/7wpgGc) or explicitly prove that the
distributed multiplications are also nsw
(https://alive2.llvm.org/ce/z/wef9su).

Fixes https://github.com/llvm/llvm-project/issues/66066.
