We no longer have a need to support ppc64le, nor do we have any testing story for the assembly we previously had. Remove all ppc64le-specific assembly. This CL stops short of removing it from base.h. That'll be done in a follow-up CL, just to separate which removals are for the assembly and which removals remove all support. Update-Note: After this change, ppc64le builds drop assembly optimizations and will fallback to a generic C-based AES implementation.
