CGDebugInfo: Use DIBuilder API for self-referencing DICompositeTypes Use new `DIBuilder` API from LLVM r224482 to mutate `DICompositeType`s, rather than changing them directly. This allows `DIBuilder` to track otherwise orphaned cycles when `CollectContainingType()` creates a self-reference.

IR: Add 'distinct' MDNodes to bitcode and assembly (clang) Update testcases for LLVM change in r225474 to make `MDNode`s explicitly distinct (when they aren't uniqued).
