    fortran: ICE using undeclared symbol in array constructor PR93484

    Using undeclared symbol k in an expression in the following
    array constructor results in an ICE:

        print *, [real(x(k))]

    If the call to the intrinsic is not in a constructor a no IMPLICIT
    type error is reported and the ICE does not occur.

    Matching on an expression instead of an initialisation express an
    and not converting a MATCH_ERROR return value into MATCH_NO results
    in the no IMPLICIT error and no ICE.

    Note: Steven G. Kargl  <kargl@gcc.gnu.org> is the author of the
    changes except for the test cases.
