Both tests fail.

optimized-stack-trace fails because in FrameSummary, the bytecode offset
translated from the PC of the optimized frame is wrong. I suspect that using the
bailout id is off-by-one. The bailout id is supposed to be the bytecode offset
where we would continue after deserialization, but that's not the equivalent to
the current instruction. If I use bailout id minus 1, then the test passes.

optimized-debug-frame fails because the FrameInspector does not correctly
translate PC on the optimized frame to a bytecode offset.

Thanks for the tests and also looking into why they fail. I found a couple of
more tests that fail because the bytecode offset is wrong. I will try to fix it.


lgtm.

Thanks,
Mythri
