Massive PORTS_REVISION bump after making gcc-9.1 default

[Kevin Oberman]

Today I was hit with 226 ports needing update. With one exception, all were
the result of the bump or the default gcc version to 9.1. The problem is
that 9.1 was not installed first, so over 43 of these ports were rebuilt
with the exact same compiler it was built with before the rebuild, eating
up 2:45 of time on my build system. I'm sure if was less for many as my
build system is over 8 years old. It was non-trivial in any case.

Should an install of gcc9 preceded all updates? Perhaps a note in UPDATING?
I certainly looked there before I started when I saw 226 ports in the list.

Should I rebuild the ports that were rebuilt prior to the installation of
gcc-9.1?
