Auto merge of #66329 - ktrianta:mir-opt-unreachable-propagation, r=oli-obk
Add unreachable propagation mir optimization pass @oli-obk suggested we create a MIR pass that optimizes away basic blocks that lead only to basic blocks with terminator kind **unreachable**. This is a first take on this, which we started with @gilescope at RustFest Impl Days. The test currently fails when the compiled program runs (undefined behaviour). Is there a way to avoid running the compiled program?
