I only have a bit of it already implemented, mostly because I wasn't sure
about the best way to proceed in terms of codes.  But I'm willing to keep
working on it :-)

One thing I think will make things easier is the float code renaming I had
originally tried to submit.  I tried to count up the cases where we would need 
new codes and I don't think there are enough single letters left to do the job 
well.  Renaming the float codes will give us a significant amount of extra
room. 

The best situation would allow us to include some of the completers in the
opcode name itself, but I don't see how that will work easily.

Are you making the new syntax active in gas at all levels or just 2.0?
