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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78477 91177308-0d34-0410-b5e6-96231b3b80d8
