[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 bug7;

class love { }
void bug() {
    love[] child;
    child.length=1;
    assert(child[0] is null);
    child[0]=null;
    assert(child[0] is null);
}
void main()
{
    bug();
}
