Ordering of instructions in optable.xml is random from SSSE 3 on about udis86 HOT 3 OPEN

Having looked more carefully through the existing optable.xml, I think the intent is to organize each section alphabetically by functional mnemonic and then by increasing operand width within each functional mnemonic. For example, this leads to the ordering and, andps, andpd, andnps, andnpd ('and' and 'andn' being distinct functional mnemonics) rather than and, andnpd, andnps, andpd, andps. I am going to go ahead and reorder the SSE sections according to this structure.

The intent so far has been to order by functional mnemonic within a section. Going forward I'd like drop these section/grouping and take one of two approaches

(a) Order by functional mnemonic only. Use class tags for information about the instructions for the reader.

(b) Split the optable.xml into <major_class>.xml: sse.xml, sse2.xml, avx.xml

I don't like the groupings and they serve little purpose. Also, I'd discourage hand editing for re-orderings. The best approach would be to add the relevant class tags, and then script the re-orderings.

Sounds good to me. I like (a) better than (b). Please discard the reordering patch I sent.
