Squashed, review-friendly version of the stack from #33488. This is new version of our mutability and inference model, designed to replace the core algorithm for determining the sets of instructions involved in constructing a given value or set of values. The new model replaces InferReferenceEffects, InferMutableRanges (and all of its subcomponents), and parts of AnalyzeFunctions. The new model does not use per-Place effect values, but in order to make this drop-in the end _result_ of the inference adds these per-Place effects. I'll write up a larger document on the model, first i'm doing some housekeeping to rebase the PR.

Thanks for working on this @josephsavona！This seems like a significant improvement to the compiler's mutability model. Looking forward to seeing the follow-up documentation. |
