RFR(S): 8216556: Unnecessary liveness computation with JVMTI

[Doerr, Martin]

Hi,

I'd like to contribute a small JIT improvement for JVMTI to avoid calling raw_liveness_at_bci when its result is not needed.

Bug with description:
https://bugs.openjdk.java.net/browse/JDK-8216556

Webrev:
http://cr.openjdk.java.net/~mdoerr/8216556_JVMTI_liveness/webrev.00/

Please review.

Best regards,
Martin
