The reason of the assertion is that in inline native clone intrinsics, the reexecute
bit was not set for the null check at the very beginning, and then set to true for
allocation and copy. Both the null check and the later part may raise exceptions, and
thus the assertion on two exception's jvmstates will see different reexecute bits.
