Test C, C++, Fortran interface combinations

Previously the Fortran test created a single executable containing C,
C++, and Fortran sources.  This commit divides the executable into three
libraries corresponding to each language, and two executables testing
Fortran/C only and Fortran/C/C++ together.  The result tests more
combinations of using the languages together, and that language
requirements propagate through linking.
