Add support for MOVSX/MOVSXD/MOVZX (move-with-extend)
instructions to the generic x86 emulator. Also add
preliminary support for 16-bit addressing: decode the
ModR/M byte properly but still need to access and update
implicit memory operands (esp,esi,edi) with correct width.
Work is also needed to support real-mode addressing.
