This allows dead-stripping to properly optimize away unreferenced clones
of intrinsic functions, and allows the inliner to detect intrinsic
functions that are only called once (which can generally always be
inlined without penalty).

Early returns can cause the inliner to generate suboptimal code. We
control our built-ins, so let's avoid them where we can.
Patterns like this challenge the inliner:
if (x) return y;
return z;
But this can be replaced by equivalent code that inlines better:
return x ? y : z;
Or, if a ternary can't be used, this also does a better job:
if (x) return y;
else return z;
In several cases, this allows the inliner to avoid generating a
do-while(false) block for control flow.

Several blend functions generate a surprisingly large amount of code,
and appear to have opportunities for further optimization. At any rate,
if we make compiler changes that would affect the output of a blend
function, I think we would want to see the changes reflected in our
golden outputs.
