  Log Message:
  -----------
  [StructuralHash] Refactor

 - Use stable_hash instead of uint64_t
 - Rename update* to hash* functions. They compute stable_hash locally
   and return it.

  [StructuralHash] Support Differences

This comutes a structural hash while allowing for selective ignoring of
certain operands based on a custom function that is provided.
Instead of a single hash value, it now returns FunctionHashInfo which
includes a hash value, an instruction mapping, and a map to track the
operand location and its corresponding hash value that is ignored.

  [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.

  Log Message:
  -----------
  [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.
