hasDefinitiveInitializer - Whether the global variable has an initializer, and any other instances of the global (this can happen due to weak linkage) are guaranteed to have the same initializer.
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.
