Use entry values for 32-bit PPC struct return
AdaCore has a local patch for PPC "finish", but last year, Ulrich
Weigand pointed out that this patch was incorrect. It may work for
simple functions like the one in the internal test, but nothing
guarantees that r3 will be preserved by the callee, so checking r3 on
exit is not always correct.
This patch fixes the problem using the same approach as PPC64: use the
entry value of r3, if available. Ulrich confirmed this matches the
PPC32 ABI.
