Michael Kuperstein 2a93bda6e9 [CGP] Be less conservative about tail-duplicating a ret to allow tail calls ... CGP tail-duplicates rets into blocks that end with a call that feed the ret. This puts the call in tail position, potentially allowing the DAG builder to lower it as a tail call. To avoid tail duplication in cases where we won't form the tail call, CGP tried to predict whether this is going to be possible, and avoids doing it when lowering as a tail call will definitely fail. However, it was being too conservative by always throwing away calls to functions with a signext/zeroext attribute on the return type. Instead, we can use the same logic the builder uses to determine whether the attributes work out.
