I noticed this while running test_yjit with --mjit-call-threshold=1, which redefines `Integer#<`. When Ruby is monkey-patched, MJIT itself could be broken. Similarly, Ruby scripts could break MJIT in many different ways. I prepared the same set of hooks as YJIT so that we could possibly override it and disable it on those moments. Every constant under RubyVM::MJIT is private and thus it's an unsupported behavior though.
