RFR: 8302203: IR framework should detect non-compilable test methods early

[Tobias Hartmann]

If a test method becomes non-compilable due to compilation bailouts, the IR framework will currently try to re-enqueue the method for compilation until the 10s timeout is reached (see log in bug report). Instead, we should check if the method became non-compilable and bail out immediately.

Thanks,
Tobias
