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.
