They are both passed in hardware registers and they both point to places
on the stack on function entry.  The argument pointer is *always* live
when a function is entered and this never changes, even if it isn't used.
So, from my standpoint, it seems reasonable to add it always (at least
for hppa64).

However, I believe Kenny would like a solution that avoids having to
set the register as live in the entry defs (i.e., he would like to move
away from having entry defs, etc).
