// 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.
// different elements therefore use the largest element size possible,
// merge smaller integer elements to 64 bits, and group repeated elements.
//
// 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.
// 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.
