[X86] Don't lower variable vi8/vi16 extractelt using VPERMV. This lowering was removed in r295660, but we can make a smaller change for swift-4.0 and just avoid VPERMV v64i8/v32i16, for two reasons: - VPERMV v64i8 maps to VPERMB, which requires AVX512VBMI - VINSERT v64i8/v32i16 doesn't have patterns and fails to select too. rdar://32988165
