When running the code below, the float 2 should be stored yet it isn't. On
Linux, the output is 4 lines of -nan, on Mac, the output is 4 lines of 0.0:

import core.simd;
import std.conv;
import std.stdio;

void main() {
  float4 fl = 2;
  foreach(f; fl.array)
    writefln("%f", f);
}

This is preventing a lot of work from being able to be done on the simd
libraries.  Algorithms like sin, cos, require a lot of literal constants to
function, let alone several hundreds of constants  for a comprehensive set of
unit tests.
