01c99892ca [X86] Disassembler support for move to/from %rax with a 32-bit memory offset is REX.W and AdSize prefix are both present.

71fc42dbf6 [X86] Make the instructions that use AdSize16/32/64 co-exist together without using mode predicates.
This is necessary to allow the disassembler to be able to handle AdSize32 instructions in 64-bit mode when address size prefix is used.

Eventually we should probably also support 'addr32' and 'addr16' in the assembler to override the address size on some of these instructions. But for now we'll just use special operand types that will lookup the current mode size to select the right instruction.

3bc4397f1f [X86] Remove the single AdSize indicator and replace it with separate AdSize16/32/64 flags.
This removes a hardcoded list of instructions in the CodeEmitter. Eventually I intend to remove the predicates on the affected instructions since in any given mode two of them are valid if we supported addr32/addr16 prefixes in the assembler.

9334b07527 [x86] Fix disassembly of MOV16ao16 et al.
The addition of IC_OPSIZE_ADSIZE in r198759 wasn't quite complete. It
also turns out to have been unnecessary. The disassembler handles the
AdSize prefix for itself, and doesn't care about the difference between
(e.g.) MOV8ao8 and MOB8ao8_16 definitions. So just let them coexist and
don't worry about it.

aab59870a4 [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?

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.
