c++: Handle multiple aggregate overloads [PR95319].

Here, when considering the two 'insert' overloads, we look for aggregate
conversions from the same initializer-list to B<3> or
initializer_list>.  But since my fix for reshape_init overhead on the
PR14179 testcase we reshaped the initializer-list directly, leading to an
error when we then tried to reshape it differently for the second overload.

gcc/cp/ChangeLog:

PR c++/95319
* decl.c (reshape_init_array_1): Don't reuse in overload context.

gcc/testsuite/ChangeLog:

PR c++/95319
* g++.dg/cpp0x/initlist-array12.C: New test.

Confirmed, started with r10-6388-ge98ebda074bf8fc5.

Reduced test-case:

$ cat pr95319.ii
namespace std {
template  class initializer_list {
  int *_M_array;
  unsigned long _M_len;
};
template  struct A { typedef int _Type[_Nm]; };
template  struct B { typename A<_Nm>::_Type _M_elems; };
class C {
public:
  void insert(int, B<3>);
  void insert(int, initializer_list>);
};
} // namespace std
int a;
int
main() {
  using ArrayVector = std::C;
  auto b = ArrayVector();
  b.insert(a, {{2}});
  return 0;
}
