Fix a bunch of cases where we use the same external name to mean multiple different things in the same test. We've historically gotten away with this, but under `--share-cpp-ast`, it becomes an error, at least if the entity is either defined in, or used from, C++ code. Assisted-by: Gemini via Antigravity (original change) and Claude Code (suggested edits in review) --------- Co-authored-by: Chandler Carruth <chandlerc@gmail.com>
