I'm trying to get a feel for what the LLVM community wants to get out of 
path profiles.  Ball Larus path profiles contain counters for path 
numbers, but this raw information is not too useful.   Some potential 
queries follow:
- Given a path number, and function give a basic block iterator over the 
- Given a function give path numbers ordered by counts.
- Given a basic block give path numbers such that the basic block is in 
each path ordered by counts.
Which queries would you like to have?
