PR c++/53609 - Wrong variadic template pack expansion in alias template

Consider this example:

     2 template<int T> struct Z {static const int value = T;};
     3 template<int...T> using LZ = List<Z<T>...>;

     6 struct F

     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

 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.

libstdc++: Add mem_order_hle_acquire/release to atomic.h v2
