STDCXX-101
* instantiation_before_definition.h: Avoided using the extern template
extension to declare an explicit instantiation of a function template
when _RWSTD_NO_EXTERN_FUNCTION_TEMPLATE is #defined.
* EXTERN_TEMPLATE_BEFORE_DEFINITION.cpp: Established a dependency on
the EXTERN_FUNCTION_TEMPLATE.cpp test.
* EXPLICIT_INSTANTIATION_BEFORE_DEFINITION.cpp: Same.
