Because that would also perform this transformation on external functions and
other functions that are intrinsically alive (Since we don't store that they
are intrinsically alive, only that all of their return values and arguments
are).

On second thought, however, it might be better to store intrinsically
alive functions as such, which should also reduce the size of the Uses map and
reduce lookup times.

I think Dan pointed this out somewhere as well, I didn't get around to fixing
those yet :-)
