2017-02-03PR libstdc++/60936 reduce coupling between objects in libstdc++.aJonathan Wakely17-194/+406
Move explicit instantiation definitions for string I/O functions into their own files so that iostream and locale definitions are not needed for uses of strings without I/O. Move functions for throwing C++11 exceptions into the individual files defining the exception types, so that using any of the functions from functexcept.cc doesn't pull in large pieces of the C++11 library. Finally, avoid using __int_to_char in snprintf_lite.cc to avoid pulling in locale-inst.cc for one function.
