What is working for you?
With the original fortran test I get
% gfc pr89204.f90 -O2 -floop-interchange
% time ./a.out
35.970u 0.081s 0:36.76 98.0% 0+0k 0+0io 0pf+0w
If I move the 'i' do loop inside the nested loops I get
% gfc pr89204_db.f90 -O2
% time ./a.out
8.124u 0.025s 0:08.76 92.9% 0+0k 0+0io 0pf+0w

When interchange happens you should see sth like
"loops interchanged in loop nest"
when compiling with -fopt-info-loop. But it doesn't do that for the fortran
case.

You're wasting your time. Chinoune closed this and
other PRs that s/he submitted because of a temper
tantrum. S/He's upset that
https://gcc.gnu.org/pipermail/gcc-bugs/2021-January/724765.html
was closed as INVALID because the behavior documented
in the manual does not meet his/her expectations. S/He refuses
to accept that gfortran has selected processor-dependent behavior
that does is different than Intel Fortran. Note Intel Fortran
documents it choice, but does not conform to its own documentation.
Just open a new PR with a Depends On reference to this PR.
