  Log Message:
  -----------
  Don't report memory return values on MacOS_arm64 of SysV_arm64 ABI's.

They don't require that the memory return address be restored prior to
function exit, so there's no guarantee the value is correct.  It's better
to return nothing that something that's not accurate.
