New OptimizationRemarkEmitter pass for MIR This allows MIR passes to emit optimization remarks with the same level of functionality that is available to IR passes. It also hooks up the greedy register allocator to report spills. This allows for interesting use cases like increasing interleaving on a loop until spilling of registers is observed. I still need to experiment whether reporting every spill scales but this demonstrates for now that the functionality works from llc using -pass-remarks*=<pass>.
