Bug #18232: Ractor.make_shareable is broken in code loaded with RubyVM::InstructionSequence.load_from_binary
https://bugs.ruby-lang.org/issues/18232#change-94154

* Author: byroot (Jean Boussier)
* Status: Closed
* Priority: Normal
* ruby -v: ruby 3.0.2p107, ruby 3.1.0dev
* Backport: 3.0: DONE
----------------------------------------
This was first reported as a Bootsnap bug: https://github.com/Shopify/bootsnap/issues/376

But I reduced it to:

```ruby
source = <<~RUBY
  x = :foo
  pr = Proc.new { p x }
  Ractor.make_shareable(pr)
  pr.call
RUBY
RubyVM::InstructionSequence.compile(source).eval # :foo
RubyVM::InstructionSequence.load_from_binary(RubyVM::InstructionSequence.compile(source).to_binary).eval # false
```

The bug is present on both 3.0.2 and 3.1.0-dev. I have no idea what might cause this.
