Instead of 2 * LONG_TYPE_SIZE. POINTER_SIZE is believed to be the
correct base on more configurations than LONG_TYPE_SIZE and this
adjustment prevents the need for local patches to compensate on
configurations where the latter is inappropriate, for example
x86_64-mingw.

gnattools build machinery uses just-build xgcc and xg++ as $(CC) and
$(CXX) in native builds. However, if C and C++ languages are not
enabled, it won't find them. So, enable C and C++ if Ada is enabled.
Most of the time, this is probably no big deal: C is always enabled
anyway, and C++ is already enabled for bootstraps.
We need not enable those for cross builds, however. At first I just
took the logic from gnattools/configure, but found it to be lacking:
it would use the just-built tools even in cross-back settings, whose
tools just built for the host would not run on the build machine. So
I've narrowed down the test to rely on autoconf-detected cross-ness
(build->host only), but also to ensure that host matches build, and
that target matches host.
I've considered sourcing ada/config-lang.in from within
gnattools/configure, and testing lang_requires as set by it, so as to
avoid a duplication of tests that ought to remain in sync, but decided
it would be too fragile, as ada/config-lang.in does not expect srcdir
to refer to gnattools.

This change is aimed at getting rid of spurious -Wuninitialized warnings
issued for small records passed by copy and containing default values
for some of their components.
The source of the problem is that the _Init parameter of the
initialization routine is declared as an in/out parameter, so the
uninitialized object is passed by copy to it and this can be flagged by
-Wuninitialized.
That's why the mode of the parameter is changed to out, except for the
cases where information really needs to be passed in: unconstrained
array types, protected and task types.
For the following record type Rec!
type Rec is record
B : Boolean := True;
end record;
the initialization routine must now be:
procedure r__recIP (_init : out r__rec1) is
begin
_init.b := true;
return;
end r__recIP;

VxLink is a helper tool used as a wrapper around g++/gcc to build
VxWorks DKM (Downloadable Kernel Modules).
Such DKM is a partially linked object that includes entry points for
constructors and destructors.
This tool thus uses g++ to generate an intermediate partially linked
object, retrieves the list of constructors and destructors in it and
produces a C file that lists those ctors/dtors in a way that is
understood be VxWorks kernel. It then links this file with the
intermediate object to produce a valid DKM.

With -gnateS, the Ada compiler sets itself up to output discriminators
for different instantiations of generics, but the middle and back ends
have lacked support for that. This patch introduces the missing bits,
translating the GNAT-internal representation of the per-file instance
map to an instance_table that maps decls to instance discriminators.
