use global cache when computing proof trees we're writing the solver while relying on the existence of the global cache to avoid exponential blowup. By disabling the global cache when building proof trees, it is easy to get hangs, e.g. when computing intercrate ambiguity causes. Removes the unstable `-Zdump_solver_proof_tree_use_cache` option, as we now always return a full proof tree. r? `@compiler-errors` |
