  [lldb] Avoid returning a stale AddressOf (#212915)

The 'ValueObject::AddressOf()' method assumes that the address of a
value object cannot change, so when it is calculated once, it does not
need to be updated afterwards. However, this is not the case if the
'ValueObject' is a dependent object obtained by calling 'Dereference()'
of another 'ValueObject'. If the latter object is changed, the dependent
value object should return a new address from the 'AddressOf()' method
to reflect the change.
