Hi Alex.  Yes, that work is still ongoing.  I had to rewrite the type inference from scratch in CodeGenDAGPatterns.cpp and that part works, at least in the sense of preserving the existing behavior (i.e. for patterns that do not use variable classes).  What's left is to change the TargetRegisterClass structure and the register info emitter.  This is taking time since now it has a much wider scope than it had in the first approximation.
