[Werner Lemberg]

branch: master
commit c37c08738260e267764b6d6a8d4469eaa1e6568a

    Guard inclusion of emmintrin.h
    
    Guard inclusion of emmintrin.h with "#ifdef __SSE2__". The gcc version
    of this header, xmmintrin.h, and mmintrin.h check that the appropriate
    defines are set before defining anything (are internally guarded).
    However the clang versions of these includes are not internally guarded.
    As a result of this, externally guard the inclusion of these headers.
