Latest PermGen elimination webrev

[John Rose]

I have made an initial merge of a recent snapshot of the PermGen work with the JSR 292 changes.

If you are are involved in permgen or 292, please have a look at this early version:

  http://cr.openjdk.java.net/~jrose/7023639/webrev.permgen.00/

This version barely compiles.  I have not tested it yet, but I think it has substantially the correct contents.

Note that this version does not take into account recent changes (which have been small, I think) to either the hotspot-comp or permgen baselines.  The patch gives precisely the versions it bridges, as follows:
