GDB 10 branching - 2020-06-27 Update

[Joel Brobecker <brobecker@adacore.com>]

Hi everyone,

Great progress last week, as the first section of this report will
indicate! So far, we're down to 3 identified issues we would like
to fix before branching. As always, if you see anything else that
you think should make the list, please let us know!

As a reminder, the proposal was to try to branch during the weekend
of July 4th if we can, which is very soon. From there, we would then
aim for a release 2-3 weeks later.

    (inline frames hanlding). Andrew provided in his commit revlog
    a very detailed explanation of the situation.
