"The MMX_MASKMOVQ and MMX_MASKMOVQ64 instructions are labeled as MRMDestMem
...
instructions, which implies that there is an explicit memory operand. There is
(however) no explicit memory operand; although this is a store, the only memory
operand is implicit, indicated by DS:EDI. This causes the table-generation code
for the disassembler to report an error."

also some contribution from Jim Grosbach, Bob Wilson, and Evan Cheng.
I've done my best to consolidate the patches with those that were done by
Viktor Kutuzov and Anton Korzh from Access Softek, Inc. Let me know if missed
anything. I've completely reorganized the thumb2 td file, made more extensive
uses of multiclass, etc.
Test cases will be contributed later after I re-organize what's in svn first.
