Several VEC member functions that accept an element 'T' used to have
two overloads: one taking 'T', the second taking 'T *'.

This used to be needed because of the interface dichotomy between
vectors of objects and vectors of pointers.  In the past, vectors of
pointers would use pass-by-value semantics, but vectors of objects
would use pass-by-reference semantics.  This is no longer necessary,
but the distinction had remained.

The main side-effect of this change is some code reduction in code
that manipulates vectors of objects.  For instance,

-  struct iterator_use *iuse;
-
-  iuse = VEC_safe_push (iterator_use, heap, iterator_uses, NULL);
-  iuse->iterator = iterator;
-  iuse->ptr = ptr;
+  struct iterator_use iuse = {iterator, ptr};
+  VEC_safe_push (iterator_use, heap, iterator_uses, iuse);

Compile time performance was not affected.

Tested on x86_64 and ppc64.

Also built all-gcc on all targets using VEC routines: arm, bfin, c6x,
epiphany, ia64, mips, sh, spu, and vms.

While working on something else, I noticed that debug_tree (vec), when
vec is a TREE_VEC was crashing because TREE_NOTHROW was asserting that
its argument is not a TREE_VEC, so print_node would crash.

It turned out that TREE_NOTHROW was accidentally modified by this
change set:

Merge from cxx-conversion branch (http://gcc.gnu.org/wiki/cxx-conversion).

As described in http://gcc.gnu.org/ml/gcc/2012-08/msg00015.html, this patch
changes the default bootstrap process so that stage 1 always builds with a C++
compiler.

Other than the bootstrap change, the patch makes no functional changes to the
compiler.  Everything should build as it does now in trunk.  The main
changes in this patch are:

1- Configuration changes.
2- Re-write of VEC.
3- Re-write of gengtype to support C++ templates and
   user-provided marking functions.
4- New hash table class.
5- Re-write double_int.
6- Implement tree macros as inline functions so they can be
   called from gdb.

As discussed before, several of these changes do not fully change
the call sites to use the new APIs.

The bootstrap changes have already been tested on a wide range of
targets (http://gcc.gnu.org/wiki/CppBuildStatus).  Additionally,
I have tested the merged trunk on: x86_64-unknown-linux-gnu,
mips64el-unknown-linux-gnu, powerpc64-unknown-linux-gnu,
i686-pc-linux-gnu, and ia64-unknown-linux-gnu.
