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.

Fixed thus, and tested against trunk on x86_64-unknown-linux-gnu.
