EA push progress

[Vladimir Kozlov]

Chuck reviewed all my changes I already pushed and 6667620.
Tom reviewed 6667615, 6667620, 6672848.

I was able to push 6667620. And I hope to push 6667615
which is in the queue now.

6672848 changes causes deoptimization problem with current
escape analysis code (jprt test run with -XX:+DoEscapeAnalysis).
I may be missing some changes from my EA workspace for it to work.
So I need more time to investigate it.

Note, previous changeset 6667615 works fine with -XX:+DoEscapeAnalysis
and I am trying to keep such compatibility with old EA code
until I change it.

Thanks,
Vladimir
