The patch looks good to me, though IMHO only the first hunk is strictly
necessary (and pretty much obvious and matches what the code was doing before
r184110).
The second hunk is just an optimisation, so supposedly it should go only to
4.8?

Can you please post it to gcc-patches and libstdc++ mailing lists where review
should happen?  Thanks.
