[J3] RESULT's lower_bound with CFI_section

[Tobias Burnus]

Hello all,

it is probably already hidden somewhere, but what's the
resulting lower bound of RESULT after calling CFI_section?

In Fortran, it is resolved via the lbound definition,
which is also invoked for pointer assignment.

I think it should be 0 for consistency, but I do not see
where it is spelled out.
