// This file implements the Mapper piece of the clang-doc tool. It implements
// a RecursiveASTVisitor to look at each declaration and populate the info
// into the internal representation. Each seen declaration is serialized to
// to bitcode and written out to the ExecutionContext as a KV pair where the
// key is the declaration's USR and the value is the serialized bitcode.
