Handle the case of a tail recursion in which the tail call is followed
...
by a return that returns a constant, while elsewhere in the function
another return instruction returns a different constant. This is a
special case of accumulator recursion, so just generalize the existing
logic a bit.

Fix PR7328: when turning a tail recursion into a loop, need to preserve
...
the returned value after the tail call if it differs from other return
values. The optimal thing to do would be to introduce a phi node for
the return value, but for the moment just fix the miscompile.
