More ProfileInfo improvements.

 - Part of optimal static profiling patch sequence by Andreas Neustifter.

 - Store edge, block, and function information separately for each functions
   (instead of in one giant map).

 - Return frequencies as double instead of int, and use a sentinel value for
   missing information.
