  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.
