[PATCH 0/7] fortran: array descriptor part 1: Move existing functions to a separate file [PR122521]

[Paul Richard Thomas]

Hello Mikael,

I am very glad to see this resubmission. Equally, I am happy with your
assurance that tis version is only trivially different from the
previous one.

>From me, OK for mainline.

Thanks to you and TF for this work.
