After spending a few minutes looking at things, I now have an
opinion...

VAX is, historically, a very important target.  For a long time (and
perhaps even now), it was considered to be the canonical example of a
CISC architecture.

Support still exists in GCC, though it's not clear to me if it
actually works.  I saw recent patches (from April, 2019) from someone
who is trying to get VAX support in GCC to work again.

Given that GCC still has code which provides VAX architecture
support, I think that GDB should do likewise.  I think that we
should attempt to not break it (anymore than it's already broken?),
but I also don't think we should attempt to test it beyond making
sure that it still builds.
