[qfcc] Improve readability of flow vars in live 

I could never remember what any of the numbers meant. While define is
still a little fuzzy (they're (pseudo)statement numbers), at least now
I'll always know that the numbers are the define set. Also, having the
flow address of the variable helps with understanding the reaching defs
output.
