Review Request: Zero and Shark fixes

[Gary Benson]

Hi all,

This webrev contains a bunch of fixes for Zero and Shark:

  http://cr.openjdk.java.net/~gbenson/zero-shark-fixes-04/

Firstly, changes to tiered compilation required fixes to allow
Shark to build.  Secondly, my fix for 7030207 uncovered a bug in
the C++ interpreter where finalizers were not being registered.
I can split the webrev into two if you'd like.

I don't have a bug id for this.

Cheers,
Gary
