Summary: When writing a loop pass I made a mistake and hit the assertion "Unreachable block in loop". Later, I hit an assertion when I called `BasicBlock::eraseFromParent()` incorrectly: "Use still stuck around after Def is destroyed". This latter assertion, however, printed out exactly which value is being deleted and what uses remain, which helped me debug the issue. To help people debugging their loop passes in the future, print out exactly which basic block is unreachable in a loop.
