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.

If the value is a global constant, its value is immutable throughout the runtime execution of the program.
Assigning a value into the constant leads to undefined behavior.

setInitializer - Sets the initializer for this global variable, removing any existing initializer if InitVal==NULL.
If this GV has type T*, the initializer must have type T.
