bug#43275: Upgrade antlr-mode to latest version

[Stefan Kangas]

Dear Christoph,

The last time we discussed this was three years ago, and this fell off
my radar.  I'm hoping we could pick up the thread now.

Did you make any progress with merging the changes in Emacs into your
tree?  I think this is still blocking merging the latest version of
antlr-mode into Emacs.

I think the best workflow here is that you merge all changes you like,
release that as a new version 3.1.6, and then we can just install that
version into Emacs.

The other option is that we do the work of merging the changes and send
a new proposed version 3.1.6 to you.  Supposedly, you will then want to
release it on SourceForge.  It will be harder for you to review any
changes on the Emacs side, of course, and it will be a bit more
error-prone since the merge isn't handled by the person that knows the
code best.

Thanks in advance.
