This revision now requires changes to proceed.

We also have TailMerging (part of BranchFolding) which should merges equivalent instruction sequences going to a return and is enabled by default. Apparently it doesn't catch the case in loop-search.ll (and you didn't provide additional examples/tests unfortunately) but we should better search for bugs there instead of adding a new pass.
