Benjamin Kramer e7e5235726 Clean up ProfileDataLoader a bit. 
- Overloading operator<< for raw_ostream and pointers is dangerous, it alters
  the behavior of code that includes the header.
- Remove unused ID.
- Use LLVM's byte swapping helpers instead of a hand-coded.
- Make ReadProfilingData work directly on a pointer.

No functionality change.
