g++.eh/crash3.C fixed thus.  The only other compiler crashes I
see are g++.oliva/template7.C and g++.other/crash15.C. 

There were a handful of eh execution failures.  Not enough to
make me believe sjlj is completely broken, but enough to think
something's not quite right.  I have not yet looked into them.
