This patch extends the typed lowering with a specialized version of 'instanceof' that is used if the "class", i.e. the constructor function, is a known constant.
Unittests check that replacement occurs as intended. Functional correctness is ensured by extensive unit tests covering instanceof already in the testsuite.
