A forward-declared C++ class in view binds to the one definition of that qualified name, by the one-definition rule; with several definitions, to the one whose file includes the declaration. C tags have no linkage and stay abstained. A forward in view outranks a short-name match in another namespace, which removes false edges such as lldb's Stream to llvm::yaml::Stream. Color::RED, gfx::Blend::ADD and typedef'd enum values bind.
Repairs: an #include in an enum body beside a #define no longer breaks the rest of the file; a brace opened in one #ifndef block and closed in another, as DeclSpec.h does, no longer costs the file its namespace; #include inside a namespace is read. Whole llvm-project: CALLS 647,135 to 654,085, USAGE 970,146 to 1,015,783, rc 0, 603 s, no quarantine. Changed relations sampled from source: no wrong edge.
