    Fix ICE on warning with new interface check.

    In the test case, there was a warning about INTENT where an EXTERNAL
    masked an interface in an outer scope, when the location of the
    symbol was not set, leading to an ICE.

    Two problems, two-part solution: It makes no sense to warn about
    INTENT for artificially generated formal argument lists, and the
    location should be set.

            about INTENT for artificially generated variables.
