Added back a bunch of static's to gen/classes.cpp, it's not superfluous, it makes the functions internal to the compilation unit, and we don't call them anywhere else.

module bug44;

struct rgb
{
    long l;
}

void foo()
{
}

rgb test() {
  scope(exit) foo();
  return rgb();
}

void main()
{
    rgb r = test();
}
