> r643030 commit (the patch from HARMONY-5495) introduces assertions for incorrect instruction
prefix sequence.
> Native stack unwinding heuristics tries to disassemble several consequent memory locations,
and expects that decoder returns error status for incorrect instructions.
> So asserts should be removed; error should be returned instead.
> Suggested patch fixes the problem; it also removes several asserts commented in HARMONY-5490
patch.
