    generate: Improve classification of pointer arguments
    
    If an argument is of a fundamental type, the direction is out or in-out,
    and it has a single pointer, then we don't need to classify it as a
    pointer argument, as it's really an out argument, and the fact that it
    uses a pointer is merely how C implements out arguments.
