class SyntaxTree::YARV::OptPlus

### Summary

‘opt_plus` is a specialization of the `opt_send_without_block` instruction that occurs when the `+` operator is used. There are fast paths for if both operands are integers, floats, strings, or arrays. It pops both the receiver and the argument off the stack and pushes on the result.
