This adds a new xtreme-header testcase to ensure that we have no
regressions with regards to exposures of TU-local declarations
in the standard library header files.
A more restrictive test would be to do 'export extern "C++"' here, but
unfortunately the system headers on some targets declare TU-local
entities, so we'll make do with checking that at least the C++ standard
library headers don't refer to such entities.
Looks fine, please squash this with the patch that adds the warning.
