Proposed updates to the gcc forge repositories

Hi everyone,
I'm planning to make some changes to the forge gcc repositories.
This is a heads-up to let you know what I plan on doing, and to give you 
a chance to comment if you have any concerns and propose an alternative 
plan.

I plan on doing this next week, likely on Wednesday June 15 (if there's 
no pushback).

What you need to do on Wednesday: update your local clones and bookmarks 
to point to the new repository location.

I plan on:
- Renaming gcc/gcc-TEST to gcc/gcc (to make it clear it's a bit less of 
a test)
- Renaming gcc/gcc-mirror to gcc/gcc-archive (because this will keep all 
the branches and tags that are being removed from the renamed gcc/gcc 
repository)
- Removing the following branches from the renamed gcc/gcc repository 
(which likely belong in a fork) (the list of what will be left is below!):

On a separate note, I've been debating whether to just remove master and 
trunk branches and use "main".
It's the default in git. This would be synced automatically from the 
current trunk branch in sourceware.org.
Given this might open multiple cans of paint for the bike shed, please 
state if you violently disagree separately from the above!

Cheers,
Claudio
