KVM: x86: Distinguish between stack operation and near branches

commit 58b7075d059f7d37ca86c76fb1446fa3447b9f4f upstream.

In 64-bit, stack operations default to 64-bits, but can be overriden (to
16-bit) using opsize override prefix. In contrast, near-branches are always
64-bit.  This patch distinguish between the different behaviors.
