rustc_llvm: Add a `-Z print-llvm-stats` option to expose LLVM statistics.
LLVM has a neat [statistics] feature that tracks how often optimizations kick in. It's very handy for optimization work. Since we expose the LLVM pass timings, I thought it made sense to expose the LLVM statistics too. [statistics]: https://llvm.org/docs/ProgrammersManual.html#the-statistic-class-stats-option
