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

From: Mikael Morin <[email protected]>

This is an update of the series posted just before the end of stage 1 in
october:
https://gcc.gnu.org/pipermail/fortran/2025-October/063053.html
https://gcc.gnu.org/pipermail/gcc-patches/2025-October/699114.html

I have added references to the PR opened to track the full patch series,
rebased on current master, and made a couple of whitespace or ChangeLog
fixes.  The patches are otherwise unchanged.

The originally posted patches have been approved last year already; I plan
to push this series next week under that approval.

This starts a series of patches (funded by STF) to refactor initialisation
and updates of array descriptors.

The current API touching array descriptors is mostly limited to a set of
getters to pick the value of individual array descriptor fields, and setters
to update them.  This requires every area of the compiler touching array
descriptors to have knowledge of their contents.

The final goal of the patches is to remove (most of) the setters from the
public API, and replace them with more high level functions providing
complete array descriptor updates (say copy descriptor, or shift array
bounds) without leaking the detail of the fields that have their values
changed under the hood.

This first series moves the existing array descriptor functions to a
separate file.
