Subject: [PATCH] x86-64: Intel64 adjustments for insns dealing with far
 pointers

AMD and Intel differ in their handling of far indirect branches as well
as LFS/LGS/LSS: AMD CPUs ignore REX.W while Intel ones honors it. (Note
how the latter three were hybrids so far, while far branches were fully
AMD-like.)
