In C, non-static inline functions require an implementation elsewhere
(even though the body is right there in the header). It is basically
never desirable to use those as opposed to static inline ones.
// This function is a shortcut for the most common use of `cxxrtl_get_parts`. It asserts that,
// if the object exists, it consists of a single part. If assertions are disabled, it returns NULL
// for multi-part objects.
