[PATCH] D137707: Move "auto-init" instructions to the dominator of their users

[Hans Wennborg via Phabricator via llvm-commits]

hans added a comment.

It's actually worse than my repro above showed. Since "real" initialization of the sret arg can get folded in with the "auto" initialization, this patch can also cause an actually initialized return value to become uninitialized: https://bugs.chromium.org/p/chromium/issues/detail?id=1431366#c8

I'll revert this for now.
