    valgrind.h: Disable Valgrind features on x64 Visual C++ Builds
    
    ...so that builds of GLib on x64 Visual C++ can be restored, as the build
    fails in line 449 of valgrind.h as it only supports MinGW/GCC for x64
    Windows and simply will not build otherwise.  Make the x64 Visual C++
    builds compile again by defining NVALGRIND when GLib is being built for
    Windows on x64 Visual C++.
