[svn r89] Fixed a bunch of problems with template instance across multiple modules. Fixed initialization of function local static variables, with a non const initializer (now happens on first call using a global to make sure it only happens once.)

module bug47;

bool func(bool a, bool b)
{
    if (a) b = false;
    return b;
}

void main()
{
    assert(func(0,0) == 0);
    assert(func(0,1) == 1);
    assert(func(1,0) == 0);
    assert(func(1,1) == 0);
}
