Currently -march=native selects -march=broadwell on Kaby Lake systems,
since its model numbers are missing from the switch statement. It falls
back to the default case and chooses -march=broadwell because of the
presence of the ADX instruction set.

Please commit them for 4.8.
For 4.7 and 4.6 please consider committing my patch
"[PATCH] arm: Fix iwmmxt shift and logical intrinsics (PR 35294)."
which only fixes the logical and shift intrinsics.

The x86/amd64 mmintrin.h provides the _mm_empty intrinsic for the 'emms'
MMX instruction. Although ARM does not need such an instruction, we
should provide an empty _mm_empty function nonetheless for source
compatibility.
