class SyntaxTree::YARV::OptNEq

### Summary

‘opt_neq` is an optimization that tests whether two values at the top of the stack are not equal by testing their equality and calling the `!` on the result. This allows `opt_neq` to use the fast paths optimized in `opt_eq` 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.

### Usage

~~~ruby 2 != 2 ~~~
