We currently do not run any of our JIT test runs with invokedynamic enabled. Had we been doing so, we probably would have caught #3950 and other recent issues with our indy logic.

This bug is a placeholder for getting indy enabled for our JIT runs, as additional runs.

I will start this by getting test:jruby:jit running with indy, since I added a test for #3950 within that suite.

This isn't a requirement for 9.1.3.0 but it would roust out some probably-easy-to-fix bugs.
