  Log Message:
  -----------
  [clang][clang-scan-deps] Add support for extracting full module dependencies.

This is a recommit of d8a4ef0e685c with the nondeterminism fixed.

This adds experimental support for extracting a Clang module dependency graph
from a compilation database. The output format is experimental and will change.
It is currently a concatenation of JSON outputs for each compilation. Future
patches will change this to deduplicate modules between compilations.
