[PATCH] D104597: [SimplifyCFG] Tail-merging all blocks with `ret` terminator

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

I'm pretty sure Clang generates a single return block, so this change alone probably won't affect any C/C++ benchmarks. Most of the affected tests are manually written IR, where LLVM developers tend to use multiple ret terminators for simplicity.

I believe Clang also uses a single `resume` block, but I could be wrong.
