r237748 continuation: segment-override prefixes are not invalid in long mode

Update DTrace disassembler accordingly.  The code to treat the prefixes
as null prefixes was already in place.
Although in practice compilers seem to generate only cs-prefix for use
in long NOPs, the same treatment is applied to all of cs, ds, es, ss for
consistency.
