Unnecessary splat in `normalize*` functions

[defaultgnome]

Hey folks,

I was looking through the normalize2, normalize3, and normalize4 functions and noticed this pattern:

return v * splat(F32x4, 1.0) / sqrt(dotX(v, v));

Out of curiosity, I tried removing the splat(F32x4, 1.0) since multiplying by 1 shouldn’t change the result, and everything still passes:

return v / sqrt(dotX(v, v));

Is there a reason for explicitly multiplying by splat(1.0)? am I missing something?

Look equivalent to me. I don't know why they we're written like that originally.
