All of those have been broken with recent loplugin:sequentialassign changes (and
have been found with a new plugin to be commited).

The code in SbUnoClass::Find (basic/source/classes/sbunoobj.cxx) looks
suspicious, but has been effectively like that ever since at least
c25ec060 "initial import", so just marked it
with a TODO comment for now.
