RFR(s): 8076181: bytecodeInterpreter.cpp refers to unknown labels.

[Severin Gehwolf]

Hi,

Could somebody please review and sponsor this change?

JDK-8074345 introduced new jumps to labels which were undefined in
bytecodeInterpreter.cpp. This makes release builds of Zero fail[1],
since it uses the computed goto approach rather than a switch statement
which debug builds use. AFAIK, Zero is the only remaining user of the C
++ interpreter.

The fix is to not introduce those unknown labels since they aren't
implemented anyway. Note: CDS is not implemented in Zero. I'm not
entirely sure why 8076181 touched bytecodeInterpreter.cpp in the first
place.

Thanks,
