Would you please remove the uses there as well?  I see that at least
SH is going to take a compile-time performance hit when doing
relaxation because of this change, since every function call is
indirect, and we'll have to resort to backward-scanning the
instruction stream looking for the insn that sets the register,
whereas previously we'd most often go straight to it by means of
LOG_LINKS.  I guess we can live with that...
