libiberty: Invoke D demangler when --format=auto
Investigating GDB PR d/31580 showed that the libiberty demangler
doesn't automatically demangle D mangled names. However, I think it
should -- like C++ and Rust (new-style), D mangled names are readily
distinguished by the leading "_D", and so the likelihood of confusion
is low. The other non-"auto" cases in this code are Ada (where the
encoded form could more easily be confused by ordinary programs) and
Java (which is long gone, but which also shared the C++ mangling and
thus was just an output style preference).
This patch also fixed another GDB bug, though of course that part
won't apply to the GCC repository.

libiberty
* cplus-dem.c (cplus_demangle): Try the D demangler with
"auto" format.
* testsuite/d-demangle-expected: Add --format=auto test.
