Overview

### Summary

‘opt_ge` 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 or floats. It pops both the receiver and the argument off the stack and pushes on the result.

### Usage

~~~ruby 4 >= 3 ~~~
