Latest JSR 292 performance work

It's been a long time since my last post (over a year) and in the meantime we have released JDK 7 with JSR 292 support.  Right now I'm working on JSR 292 performance and which should be included in the next JDK 7 update (7u) release.

I just sent out an email to the mlvm-dev mailing list with some JRuby performance numbers for:

7079673: JSR 292: C1 should inline bytecoded method handle adapters

I paste them here again for convenience.
