Revised proposed patch

I managed to remove most of my regression by using ALWAYS_INLINE on the helper
functions. It's about 0.3-0.4% for me right now. Any performance testing on
other machines would be greatly appreciated.

The codegen is pretty much optimal given our current framework. I will try to
run some tests and attempt to find determine whether the extra work during
codegen is actually the cause of the performance regression.
