For me, the reason to make such changes is to make the code simpler and
more robust: by avoiding conversion to/from Lisp_Object we get to use
more of C's type checks (as weak as they are, they're better than
nothing).
And for objects which are always integers, the code ends up simpler.
If it's more efficient, that's just a nice side-effect.
