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.
This reverts commit ccd8dd6ad3.
Revert "MJIT: Fix miniruby with MJIT_FORCE_ENABLE"
This reverts commit b033775ed9.
GitHub Actions is failing. I ran out of time today to investigate it.
will try it again tomorrow.
