[PATCH] D71209: InstCombine: Don't rewrite phi-of-bitcast when the phi has other users

[Connor Abbott via Phabricator via llvm-commits]

- Update precommitted test in this commit.
- Make the test match the original bug better. It turns out that in my attempt to make it harder for other transforms to happen beforehand and break the test, I accidentally made another transform kick in which broke it anyways. Use this form with a loop which should hopefully defeat other optimizations better.
