constversions of x86(64) intrinsics in stdarch.Public API
~50% of x86(64) intrinsics in stdarch are amenable to constification. Intel has some weird pecularities in floating point, especially in comparison and conversion, which will be nontrivial to constify. Most integer intrinsics have been constified.
