  [InstCombine] Reuse common code between foldSelectICmpAndBinOp and foldSelectICmpAnd. (#131902)

The commit that was removed from
https://github.com/llvm/llvm-project/pull/127905 due to the conflict
with https://github.com/llvm/llvm-project/pull/128741.

The use of common code results in that the foldSelectICmpAndBinOp also
use knownbits in the same way as was added for foldSelectICmpAnd in
https://github.com/llvm/llvm-project/pull/128741.

proof for the use of knowbits in foldSelectICmpAndBinOp:
