x86: fix AVX-512 16-bit addressing
Despite EVEX encodings not being available in real and VM86 modes,
16-bit addressing still needs to be handled properly for 16-bit
protected mode as well as 16-bit addressing in 32-bit mode. Neither
should displacements be dropped silently by the assembler, nor should
the disassembler fail to correctly scale 8-bit displacements.
