[PATCH] D63972: [CodeGen] Do the Simple Early Return in block-placement pass to optimize the blocks

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

I reverted this in rL373805 <https://reviews.llvm.org/rL373805>, it caused https://bugs.llvm.org/show_bug.cgi?id=43566, which has to do with Windows EH. This code in general doesn't seem to consider address-taken blocks, so the problem is probably wider than just Windows EH. See the bug for a test case.
