[PATCH] D153966: [SimplifyCFG] Allow dropping block that only contains ephemeral values

[Matthew Maurer via Phabricator via llvm-commits]

maurer added a comment.

I now have a pretty clean reproduction <https://gist.github.com/maurer/3056d75916e77c592f1811f1c8aaa931>.

I'm having trouble following the original patch author's heuristic for when it's safe to remove the `assume`, so I'll leave it up to them to rework it to avoid pruning load bearing assumes like this one.
