[Patch] [libstdc++] [C++0x] Export std::string base object move constructor.

[Benjamin Kosnik]

Thanks for reporting this issue Adam. Don't hesitate to file bug
reports in gcc bugzilla category libstdc++ when you find problems like
this in the future!

I made a note to correct the testsuite deficiency.

Yes please. Thanks for the quickness on this Jakub.

For the record, I just did an audit of src/*inst.cc files mapped to
include files with non-operator && usage to look for similar issues in
other classes. (Non-exported symbols required for move semantics to
function in other library areas.) I didn't find any.
