compiler: pass correct 'function' flag to circular_pointer_type

Browse source 
The code in Named_type::do_get_backend was not passing the correct
    flag value for circular function types to Backend::circular_pointer_type
    (it was always setting this flag to false). Pass a true value if the
    type being converted is a function type.
