libstdc++: Add missing feature-test macro in <memory>
Per version.syn#2, <memory> is required to define
__cpp_lib_addressof_constexpr as 201603L.
Bootstrapped and tested on aarch64-linux-gnu.
Signed-off-by: Dhruv Chawla <dhruvc@nvidia.com>
libstdc++-v3/ChangeLog:
* include/std/memory: Define __glibcxx_want_addressof_constexpr.
* testsuite/20_util/headers/memory/version.cc: Test for macro
value.
(cherry picked from commit 0e65fef8717f404cf9c85bff51bf87d534f87828)
