[PATCH] Update libstdc++ docs for library version history

[Jonathan Wakely]

This should have been added to the manual before the 6.1 release, but
better late than never.

        * doc/xml/manual/abi.xml: Document 6.0.22 library version.
        * doc/html/manual/abi.html: Regenerate.

Committed to trunk and gcc-6-branch.
