class SyntaxTree::YARV::OptAnd

### Summary

‘opt_and` is a specialization of the `opt_send_without_block` instruction that occurs when the `&` operator is used. There is a fast path for if both operands are integers. It pops both the receiver and the argument off the stack and pushes on the result.
