[InstCombine] Make InstCombiner::OptAndOp take a BinaryOperator instead of an Instruction.
The callers have already performed the necessary cast before calling. This allows us to remove a comment that says the instruction must be a BinaryOperator and make it explicit in the argument type.
Had to add a default case to the switch because BinaryOperator::getOpcode() returns a BinaryOps enum.
