This patch removes the GC zone allocator. It is not used and it
produces several regressions in the testsuite. Furthermore, it
complicates things for the plan to implement manual GC markers
(http://gcc.gnu.org/wiki/cxx-conversion/gc-alternatives#Do_GC_marking_manually).
Tested on x86_64 with standard checking, --enable-checking=gc and
--enable-checking=release.

Consider this example:
1 template<class...I> struct List {};
2 template<int T> struct Z {static const int value = T;};
3 template<int...T> using LZ = List<Z<T>...>;
4
5 template<class...U>
6 struct F
7 {
8 using N = LZ<U::value...>; //#1 This should amount to List<Z<U::value>...>
9 }
10
11 F<Z<1>, Z<2> >::N A; //#2
which G++ fails to compile, with this error message:
test-PR53609-3.cc: In instantiation of 'struct F<Z<1>, Z<2> >':
test-PR53609-3.cc:11:15: required from here
test-PR53609-3.cc:3:43: error: wrong number of template arguments (2, should be 1)
template<int...T> using LZ = List<Z<T>...>;
^
test-PR53609-3.cc:2:24: error: provided for 'template<int T> struct Z'
template<int T> struct Z {static const int value = T;};
I think this is because in #1, when we substitute the argument pack
{U::value...} into the pack expansion Z<T>..., tsubst_pack_expansion
yields Z<U::value...>, instead of Z<U::value>..., so the instantiation
of LZ amounts to List<Z<U::value...> >, instead of
List<Z<U::value>...>.
The idea of this patch is to make tsubst_pack_expansion support
substituting an argument pack (into a pack expansion) where one of the
arguments (let's call it the Ith argument) is itself a pack expansion
P. In that case, the Ith element resulting from the substituting
should be a pack expansion P'.
The pattern of P' is then the pattern of P into which the pattern of
the Ith argument of the argument pack has been substituted.
Tested on x86_64-unknown-linux-gnu against trunk.

as gen_elem_of_pack_expansion_instantiation and the change in
