KVM: x86 emulator: fix regression with cmpxchg8b on i386 hosts

commit 16518d5ada690643453eb0aef3cc7841d3623c2d upstream.

operand::val and operand::orig_val are 32-bit on i386, whereas cmpxchg8b
operands are 64-bit.

Fix by adding val64 and orig_val64 union members to struct operand, and
using them where needed.
