ISPC: DynamicLibrary test now passes on windows.

The MSVC linker needs to know what MSVC runtime a shared library
needs. ISPC objects don't have a '/DIRECTIVE' entry for the
MSVC runtime as they have no dependency on it. Therefore
we need to add a C or C++ source to each shared library so
the MSVC linker knows what runtime to embed
