[dmd-internals] Create a dmd-cxx branch on dlang/dmd

[Iain Buclaw via dmd-internals]

Well, the intention is that, although the C++ implementation is now in
an EOL state, I'll keep up the maintenance of it for a while until GDC
is in a position to switch.  It's more of a symbolic badge of approval
for the patches I've backported from the D frontend.

This could probably be started by creating a branch of v2.068,
rebasing against the last C++ commit in master, then I'll raise a PR
for all changes I've made since that point.

Iain.
