A partial survey indicates that SROA does all that ScalarRepl can do. Some ScalarRepl tests which fail are grep based and thus sensitive to the exact IR produced by the pass, others fail because SROA produces IR with fewer bitcasts (ScalarRepl produces stuff like `trunc i160 undef to i32`).

In any case, it's pretty moot: nobody uses ScalarRepl which makes it effectively dead.
