  [CGData] Stable Function Map

These define the main data structures to represent stable functions and group
similar functions in a function map.
Serialization is supported in a binary or yaml form.

  [CGData][llvm-cgdata] Support for stable function map

This introduces a new cgdata format for stable function maps.
The raw data is embedded in the __llvm_merge section during compile time.
This data can be read and merged using the llvm-cgdata tool, into an indexed cgdata file. Consequently, the tool is now capable of handling either outlined hash trees, stable function maps, or both, as they are orthogonal.
