Poorly predicted branches are an even bigger waste.

I'm not a big fan of this change and others have asked for performance
analysis to be performed.

So I'm not applying this as-is, sorry.

It's also not great to see that CLANG can't make use of the caller's
__always_unused directive to guide these warnings.
