Subject: [PATCH] Move allocator in std::string and RB tree move constructors
Authentication-results: sourceware.org; auth=none

The move constructors for strings and RB trees were not move
constructing the allocator.

	PR libstdc++/71964
	* include/bits/basic_string.h [_GLIBCXX_USE_CXX11_ABI]
	(basic_string::_Alloc_hider(pointer, _Alloc&&)): Add constructor.
	* include/bits/stl_tree.h (_Rb_tree(_Rb_tree&&)): Move allocator.
	* testsuite/21_strings/basic_string/allocator/71964.cc: New test.
	* testsuite/23_containers/set/allocator/71964.cc: New test.

Tested powerpc64-linux, committed to trunk. I will backport this to
gcc-5 and gcc-6 too, but probably not 4.9 as the branch is about to be
closed.
