libstdc++: Use correct argument type for __use_alloc [PR 96803]
The _Tuple_impl constructor for allocator-extended construction from a
different tuple type uses the _Tuple_impl's own _Head type in the
__use_alloc test. That is incorrect, because the argument tuple could
have a different type. Using the wrong type might select the
leading-allocator convention when it should use the trailing-allocator
convention, or vice versa.
libstdc++-v3/ChangeLog:
PR libstdc++/96803
* include/std/tuple
(_Tuple_impl(allocator_arg_t, Alloc, const _Tuple_impl<U...>&)):
Replace parameter pack with a type parameter and a pack and pass
the first type to __use_alloc.
* testsuite/20_util/tuple/cons/96803.cc: New test.
