[ConstraintElim] Extend checkOrAndOpImpliedByOther to handle and/or expr trees. (#117123)
This patch extends `checkOrAndOpImpliedByOther` to handle and/or trees.
Limitation: At least one of the operands of root and/or instruction
should be an icmp. That is, this patch doesn't support expressions like
`(cmp1 & cmp2) & (cmp3 & cmp4)`.

Closes https://github.com/llvm/llvm-project/issues/117107.
