Previous Stacked Borrows diagnostics were missing a lot of information about the state of the interpreter, and it was difficult to add additional state because it was threaded through all the intervening function signatures. This change factors a lot of the arguments which used to be passed individually to many stacked borrows functions into a single `DiagnosticCx`, which is built in `Stacks::for_each`, and since it wraps a handle to `AllocHistory`, we can now handle more nuanced things like heterogeneous borrow of `!Freeze` types. |
