Auto merge of #31349 - nikomatsakis:issue-31157-obligation-forest-cache, r=aturon
Have the `ObligationForest` keep some per-tree state (or type `T`) and have it give a mutable reference for use when processing obligations. In this case, it will be a hashmap. This obviously affects the work that @soltanmm has been doing on snapshotting. I partly want to toss this out there for discussion. Fixes #31157. (The test in question goes to approx. 30s instead of 5 minutes for me.) cc #30977. cc @aturon @arielb1 @soltanmm r? @aturon who reviewed original `ObligationForest`
