[PATCH] x86: Enable Intel AVX512 VP2INTERSECT instruction

[Cui, Lili]

Hi all,

This patch is about to enable support for VP2INTERSECT in binutils . which will be in Willow Cove.
About  VP2INTERSECT  details please refer to
https://software.intel.com/sites/default/files/managed/c5/15/architecture-instruction-set-extensions-programming-reference.pdf

Make check-gas is ok.

About patch details see attachment , thanks.
