target/i386: fix memory opsize for Mov to/from Seg

This commit fixes an issue with MOV instructions (0x8C and 0x8E)
involving segment registers; MOV to segment register's source is
16-bit, while MOV from segment register has to explicitly set the
memory operand size to 16 bits.  Introduce a new flag
X86_SPECIAL_Op0_Mw to handle this specification correctly.
