Implements a simple, in-memory reducer for the mapped output of the initial tool. This creates a collection object for storing the deduplicated infos on each declaration, and populates that from the mapper output. The collection object is serialized to LLVM bitstream. On reading each serialized output, it checks to see if a merge is necessary and if so, merges the new info with the existing info (prefering the existing one if conflicts exist).

For a more detailed overview of the tool, see the design document on the mailing list: RFC: clang-doc proposal <http://lists.llvm.org/pipermail/cfe-dev/2017-December/056203.html>
