Fix loplugin:redundantcast check for same-type dynamic_cast

...when the target type is a reference type and the source and target type have
different cv qualifiers.  (And fix the fallout.  And make the tests cover that
somewhat more exhaustively; and while at it also test that the plugin can cope
with dynamic_cast to void pointers, which is the only legitimate case where a
dynamic_cast can involve types that are not (pointers or references to)
non-class types.)
