[x86] Fix MOV8ao8 et al for 16-bit mode, fix up disassembler to understand
...
It seems there is no separate instruction class for having AdSize *and*
OpSize bits set, which is required in order to disambiguate between all
these instructions. So add that to the disassembler.
Hm, perhaps we do need an AdSize16 bit after all?

Various x86 disassembler fixes.
...
Add VEX_LIG to scalar FMA4 instructions.
Use VEX_LIG in some of the inheriting checks in disassembler table generator.
Make use of VEX_L_W, VEX_L_W_XS, VEX_L_W_XD contexts.
Don't let VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE inherit from their non-L forms unless VEX_LIG is set.
Let VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE inherit from all of their non-L or non-W cases.
Increase ranking on VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE so they get chosen over non-L/non-W forms.

Add a new compression type to ModRM table that detects when the memory modRM byte represent 8 instructions and the reg modRM byte represents up to 64 instructions. Reduces modRM table from 43k entreis to 25k entries. Based on a patch from Manman Ren.
