[InstCombine] Add test cases for folding (select (icmp ne/eq (and X, C1), (bitwiseop...

This is possible if C1 and C2 are both powers of 2. Or if binop is 'and' then ~C2 needs to be a power of 2.

We already support this for 'or', but we should be able to support 'and' and 'xor'. This will be enhanced by D37274.
