Another thought I had was to use get_hard_reg_initial_val() as the
official "frame pointer" and hope that gcc was smart enough to use $fp
or an address reg as appropriate. I originally wrote that for a port
that has a register somewhat like MIPS %gp, but I've never tried it
with an eliminatable register.
Although, $sp has limited offsets too, so if it's eliminatable, we
also don't need to worry about the $fp offset ;-)
