Sorry I'm not sure I understood the question.
This condition is matching globals that have an array type with 0 elements. If
the global does not have an array type or if it is an array type with a size
different from 0 this function returns false.
Maybe there is a mix from using `getValueType` vs `getType`. The first gives
the type of the initializer of the global (the value stored in the global), the
second returns the type of the global when used as a value in the llvm-ir (a
pointer type).
