These dependencies are because src/c++11/functexcept.o requires the destructors
and vtables of all exception types. By moving __throw_bad_function_call and
__throw_regex_error and __throw_future_error into separate files we can get the
testcase smaller still:

233440 gcc7-splitexcept.so

And splitting up src/c++11/system_error.o gives:

225160 gcc7-splitexcept2.so
