This isn't the same as the goal list at
Main goal is utilize of SIMD constructs in OpenMP4.0 (#2.8 in
http://www.openmp.org/mp-documents/OpenMP4.0.0.pdf and Cilk Plus (#6-8
on x86_64 by adding vector implementations of several vector math
functions (float and double versions).
which is pretty much targeting compiler.
