x86: add (adjust) XOP insn attributes

Many were lacking "prefix" and "prefix_extra", some had a bogus value of
2 for "prefix_extra" (presumably inherited from their SSE5 counterparts,
which are long gone) and a meaningless "prefix_data16" one. Where
missing, "mode" attributes are also added. (Note that "sse4arg" and
"ssemuladd" ones don't need further adjustment in this regard.)
