Unhandled mnemonics related to XMM

I initiated a recalculate minhashes in mcrit, and while it was running, I saw numerous repeats of these errors (not in this exact order):

According to the Intel documentation, they are Pseudo-ops for the opcodes CMPPD, CMPPS, CMPSD, and CMPSS. There may be more in the Intel documentation than those listed above.

Do they just need to be added to the _xmm_group in the smda/intel/INtelInstructionEscaper.py file? If so, then I am happy to make the edits and submit a PR if that would help.

Heh, interesting. Thanks for the pointer!

I just recently included all of these instructions from capstone in #48 and now there's even more. :D
I think I'll do some more digging in the capstone source to figure out where they are coming from to get a complete as possible list.

Alright, added another 200ish instructions found in various other capstone source code files, hopefully that should cover most of them now.
