Note that if you want to transform a global, you must use hasUniqueInitializer() instead, because of the *_odr linkage type.
Example:
= global SomeType* null - Initializer is both definitive and unique.
= global weak SomeType* null - Initializer is neither definitive nor unique.
= global weak_odr SomeType* null - Initializer is definitive, but not unique.
