- Split runtime and native entry tags. - Set runtime / native entry address as vm tag in stubs. - Add reverse native entry resolver (pc to name) to public API (breaking change). - Hookup reverse resolver for standalone VM (io + bootstrap + builtin natives). - Runtime entries are registered with tags. - Profiler queries for tag names via the reverse native entry resolver. - Profiler outputs named entry tags as children under parent tag (runtime or native).
