In Valhalla, the oopFactory code is being changed to account for new array shapes and attributes, so all code should call that instead.  Turns out this function is unused, so this change removes it.  Tested with tier1-7 with a ShouldNotReachHere(), then jdk/jfr tests with the removal.

Thank you for reviewing, Kim and Markus.
