      Description

        JVM runs into an assertion when running e.g. java/lang/instrument/GetObjectSizeIntrinsicsTest_id3 test:
        # Internal Error (src/hotspot/share/utilities/copy.hpp:330)
        # assert(is_aligned(to, alignment)) failed: must be aligned: 0x00000000ffd0fc31
        (called by MemAllocator::allocate_inside_tlab)

        Reason is that the interpreter messed it up during execution of an earlier 'new' bytecode. It checks the wrong bit instead of Klass::_lh_instance_slow_path_bit.
