re PR libstdc++/66017 (Undefined behaviour in std::set<long long>)
PR libstdc++/66017
* include/bits/stl_tree.h (_Rb_tree_node): Use __aligned_membuf.
(_Rb_tree_iterator, _Rb_tree_const_iterator): Support construction
from _Base_ptr.
(_Rb_tree_const_iterator::_M_const_cast): Remove static_cast.
(_Rb_tree::begin, _Rb_tree::end): Remove static_cast.
* include/ext/aligned_buffer.h (__aligned_membuf): New type using
alignment of _Tp as a member subobject, not as a complete object.
* python/libstdcxx/v6/printers.py (StdRbtreeIteratorPrinter): Lookup
_Link_type manually as it might not be in the debug info.
