@H.J. Lu I am aware, that _mm_broadcastsd_pd does the same as _mm_movedup_pd.
However, maybe others are not. 
The fact that _mm_broadcastsd_pd is listed in the intel intrinsics guide and
won't compile with GCC while all other relevant compilers (Intel, Clang, MSVC -
tested all on Godbolt) accept it is probably suboptimal.
