Subject: 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.
