class SyntaxTree::YARV::OptEq

### Summary

‘opt_eq` is a specialization of the `opt_send_without_block` instruction that occurs when the == operator is used. Fast paths exist when both operands are integers, floats, symbols or strings. It pops both the receiver and the argument off the stack and pushes on the result.
