03:01 AM Revision 271be0a2 (git): ZJIT: Implement classvar get and set (#14918)
- https://github.com/Shopify/ruby/issues/649
Class vars are a bit more involved than ivars, since we need to get the
class from the cref, so this calls out to `rb_vm_getclassvariable` and
`rb_vm_setclassvariable` like YJIT. -
