Rather than counting directly on names, we could have a DECL_DEBUG_DECL 
or something to say what variable a decl is really an alias of.

This is the equivalent of an external multimap from original program 
variables to temporaries.

I would implement this, but i don't want to do it without someone with 
global write or approval powers telling me it's the correct design 
before i did so.
