Rollup merge of #137216 - amandasystems:cheap-outlives-eval, r=compiler-errors
eval_outlives: bail out early if both regions are in the same SCC A drive-by optimisation of region outlives evaluation: if we are evaluating whether an outlives holds for two regions, bail out early if they are both in the same SCC. This probably won't make a huge difference, but the cost is one comparison of SCC indices (integers). May want a perf run, depending on how confident whomever reviewing this is!
