// shuffle_epi8 shuffles accross entire 512 bits. Shuffle usually
// doesn't cross 128 bit lane boundaries but is consistent with AVX2
// where shuffle_epi8 spans the entire vector.
//
// There are 2 areas where overhead is aconcern: constants and
// permutations.
//
// Constants need to be composed at run time by assembling individual
// elements, very expensive. The cost is proportional to the number of
// elements therefor use the largest element size possible, even by
// merging smaller values.
//
// Constants with repeating patterns can be optimized with the smaller
// patterns repeated more frequently being more efficient.
//
// Some specific constants can be very efficient. Zero is very efficient,
// 1 and -1 slightly less so.
//
// If an expensive constant is to be reused in the same function it should
// be declared as a local variable defined once and reused.
//
// Permutations cab be very exppensive if they use a vector control index,
// even if the permutation itself is quite efficient.
// The index is essentially a constant with all the baggage that brings.
// The same rules apply, if an index is to be reused it should be defined
// as a local. This applies specifically to bswap operations.
//
// Additionally, permutations using smaller vectors can be more efficient
// if the permutation doesn't cross lane boundaries ,typically 128 bits,
// ans the smnaller vector can use an imm comtrol.
//
// If the permutation doesn't cross lane boundaries a shuffle instructions
// can be used with imm control instead of permute.
