      Description

      markWord::is_unlocked() still uses biased pattern, causes fallback to klass layout

      * add more gtest mark word tests
      * assert any use of "biased locking" (there are some existing "has_biased_pattern()" asserts not guarded "UseBiasedLocking")
      * remove biased_lock_mask_in_place from is_unlocked
