    M clang/lib/AST/ComputeDependence.cpp

  Log Message:
  -----------
  [AST] Add a Dependence bitmask to use for calculations with multiple node types.

Summary:
This makes it easier/safer to add bits (error) to other node types without
worrying about bit layout all the time.

For now, just use to implement the ad-hoc conversion functions.
Next: remove these functions and use this directly.
