[patch] fix libstdc++/21609 - deprecate __gnu_cxx::array_allocator

[Jonathan Wakely]

This deprecates this GNU extension which isn't really a conforming

        * include/ext/array_allocator.h: Add deprecated attribute.

Tested x86_64-linux, committed to trunk.

I'll update the gcc-4.9/changes.html page to note this.
