...by re-enabling the code temporarily #if'ed-out in
a528392e71 "Fixed/improved
loplugin:cppunitassertequals" (and which then triggers lots of other
lopglugin:cppunitassertequal CPPUNIT_ASSERT -> CPPUNIT_ASSERT_EQUAL warnings).
For two css::uno::Reference equality comparisons in cppu/qa/test_any.cxx, it
was more straightforward to rewrite them with an explicit call to operator ==
(which silences loplugin:cppunitassertequal) than to adapt them to
CPPUNIT_ASSERT_EQUAL's requirement for arguments of identical types.
In sc/qa/unit/ucalc_pivottable.cxx, ScDPItemData needs toString, which has been
implemented trivially for now, but might want to combine that with the
DEBUG_PIVOT_TABLE-only ScDPItemData::Dump.
