 This is produced by godbolt, which apparently has AVX512 extensions, so, it's extremely compact.

 AVX512 makes it so that there's no big penalty for double precision types, which is nice.
 
-Note that permutation masks are also supplied along side code which increase binary size.
-With inlining it could be quite substantial if per object %rip relative addressing is used.

 ### Edits ###
 - Reordered to use packed vectors without swizzling when possible.
 - Eliminated redundant computations.
