[svn r292] Fixed: string switch was broken in several ways. Fixed: TypeInfo_Typedef.next was incorrect (return base of base instead of just base). Fixed: ClassInfo offset type info (offTi) had invalid offsets.

class Foo
{
    int i;
}

class Bar : Foo
{
    int j;
}

void func()
{
    scope c = new Bar;
    func2(c);
}

void func2(Bar c)
{
    c.i = 123;
}

void main()
{
    func();
}
