We actually have a fair amount of "pick expression based on size", so
with a few helper macros we could make the code look better than the
case statements too.

Something (ENTIRELY UNTESTED!) like the attached patch, perhaps?

NOTE! I only converted one single use to that "pick_size_xyz()" model.
If this actually works for clang too, we could do the others.

I guess I should just test it, since I have that clang tree.
