This is needed to support assumed size array of fortran which can have missing upperBound/count
, contrary to current DISubrange support.
Example:
subroutine sub (array1, array2)
integer :: array1 (*)
integer :: array2 (4:9, 10:*)
array1(7:8) = 9
array2(5, 10) = 10
end subroutine
Now the validation check is relaxed for fortran.
