[pypy-dev] Resume

[Hakan Ardo]

Hi,
the jit-virtual_state branch is getting ready to be merged. It fixes
the issue in test_new_virtual_member_in_bridge. However I've added a
fieldstate member to the VirtualInfo classes, which might have some
memory usage impacts? Would it be possible/a good idea to integrate
the new VirtualStateAdder in unroll.py more closely with the resume
stuff to maybe get rid of this member to use less memory?

Also, at some (later) point I would like to experiment with including
NotVirtualInfo objects in the resumedata to allow a bridge to inherit
information about non-virtuals from it's parent loop.
