JIT status: how to introspect

[Max Lapshin]

Hi.

I've tried to launch our flussonic under jit.

Thank you a lot for this work.  We got zero speedup, but perf top have
showed where we can achieve up to 20% of boost (or maybe more).


Is it possible to introspect current jit status?  Something like:


> jit:info().
#{
  calls => ...
   misses => ...
   ...
}

or what do you use to check it in runtime?
