The ucalc performance test (Test::testPerf) in sc/qa/unit/ucalc.cxx is an old performance test. We should port that to our new in-build performance tests.
See https://mmohrhard.wordpress.com/2015/09/08/performance-tests-are-now-executed-regularly-in-libreoffice/ for some details.
We should use a new test and a new namespace ("sc-core") for this test.
Copy sc/CppunitTest_sc_perfobj.mk to sc/CppunitTest_sc_perfcore.mk. Replace the sc_perfobj and scperfobj references with sc_perfcore and scperfcore.
Add the new makefile to sc/Module_sc.mk
Copy sc/qa/perf/scperfobj.cxx to sc/qa/perf/scperfcore.cxx and remove everything that is unnecessary.
