Document -Wc11-c2x-compat.
My patch that added initial C2X support and associated command-line options missed documenting -Wc11-c2x-compat although the other options were properly documented. This patch adds the missing documentation. Tested with "make info" and "make pdf". * doc/invoke.texi (-Wc11-c2x-compat): Document. From-SVN: r278510
