re PR fortran/91471 (f951: internal compiler error: gfc_variable_attr(): Bad array reference)

2019-08-17  Steven G. Kargl  <kargl@gcc.gnu.org>

	PR fortran/91471
	* primary.c (gfc_variable_attr): Remove a gfc_internal_error(),
	which cannot be reached by conforming Fortran code, but seems to
	be reachable from nonconforming Fortran code.  Treat the AR_UNKNOWN
	case as a no-op.

2019-08-17  Steven G. Kargl  <kargl@gcc.gnu.org>

	PR fortran/91471
	* gfortran.dg/pr91471.f90: New test.
