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.
