x86emul: correct far branch handling for 64-bit mode

AMD and friends explicitly specify that 64-bit operands aren't possible
for these insns. Nevertheless REX.W isn't fully ignored: It still
cancels a possible operand size override (0x66). Intel otoh explicitly
provides for 64-bit operands on the respective insn page of the SDM.
