Overview

### Summary

opt_setinlinecache sets an inline cache for a constant lookup. It pops the value it should set off the top of the stack. It uses this value to set the cache. It then pushes that value back onto the top of the stack.

This instruction is no longer used since in Ruby 3.2 it was replaced by the consolidated opt_getconstant_path instruction.
