Just haven't got back to it yet...  There's always more to get done on 
any given day than I have the time for, so I have to prioritize and some 
things get put on the back burner until I can get back to them.

OK.  Something else must be in play here.  Clobbers can be somewhat 
special in that they may not always been an operand in the usual sense. 
  ie, often they'll just be attached to the insn as an explicit blob of 
RTL, that's the only thing I can think of that would be preventing us 
from losing here.

Let's go with your original inputs + outputs + labels change and punt 
the clobbers stuff for now.
