update C++0x status table to FDIS

[Jonathan Wakely <jwakely dot gcc at gmail dot com>]

Most of this is shuffling round sub-clauses in Clause 20 Utilities and
adjusting section numbers, but I also added some missing type traits
and added a note about missing constexpr on the duration non-member
arithmetic binary operations (as pointed out by Magnus last time I
updated the table.)

I haven't actually tried making the docs from this, as I'm away from
home and don't have the docbook stylesheets on my netbook or the
compile farm machine I've been working on, so I'll test that asap and
then commit the final version and regenerate the HTML.

Please let me know if I've missed anything out or got anything wrong
(very likely, as I didn't have time to carefully review every one of
the C++0x library clauses!)
