Dan,

I tried doing a SPEC run with the new branch but none of the SPEC
programs build (x86). I'm getting various spill failures and
unrecognizable insns.

If you want I could provide the specific failures, or if you can
give me a couple of pointers into your implementation I can try
and hunt them down.
