dg-excess-errors is a very large hammer that is rarely what you want to 
use.  To filter out certain messages, it is better to use 
dg-prune-output.  So this patch removes most of the dg-excess-errors 
from the v3 testsuite, replacing some with dg-prune-output, but most 
need no replacement.

Doing this revealed that the bind/ref_neg.cc test was broken; the 
dg-error tags were missing a space before the closing }, so they were 
being ignored.  When I fix that, I find that two of the tests are failing.

I'm committing the first patch, but am holding off on the second for 
now.  Should I go ahead and commit it or would someone like to fix those 
bugs and then commit it themselves?

Doh.

I'll look at the broken tests asap, but that will be after work in
about 8 hours.  I'm ok if you want to go ahead and commit the patch,
but if you do let's warn HJ that the regression testers will see the
FAILs.

Thanks Jon. The good news is that the same happens - no actual errors 
for line 34 & 35 - also for std::tr1::bind, thus for sure we didn't 
regress in the C++0x bind...
