  Log:
    Allow specifying arbitrary MJIT flags by --jit-debug
    
    This is a secret feature for me. It's only for testing and any behavior
    with this flag override is unsupported.
    
    I needed this because I sometimes want to add debug options but do not
    want to disable optimizations, for using Linux perf.

    mjit.c
    mjit.h
    mjit_worker.c
    ruby.c
    test/ruby/test_rubyoptions.rb
