Rollup merge of #78566 - JRF63:polly, r=Mark-Simulacrum
Enable LLVM Polly via llvm-args. I think doing it this way is better than in #51061. Polly has other useful options and we probably don't want to create a `-Z` flag for each one of them.  [Benchmark](https://gist.github.com/JRF63/9a6268b91720958e90dbe7abffe20298) I noticed that `-lto` seems to interfere with polly in this specific microbenchmark, as enabling it causes the perf to drop to that of non-polly builds.
