nsLeafFrame only exists as an abstract superclass, and every subclass actually brings along its own Reflow impl, so nsLeafFrame's own impl is just dead code. This patch makes sure it's really dead code by leaving in the Reflow() decl with " = 0;" so the compiler will enforce that all concrete subclasses *do* have a more specific override (and that they don't just inherit the stub nsFrame impl from further up the ancestor chain, for example).
