Aaron Hill 40ef1d3223 Re-introduce concept of projection cache 'completion' ... Instead of clearing out the cache entirely, we store the intermediate evaluation result into the cache entry. This accomplishes several things: * We avoid the performance hit associated with re-evaluating the sub-obligations * We avoid causing issues with incremental compilation, since the final evaluation result is always the same * We avoid affecting other uses of the same `InferCtxt` which might care about 'side effects' from processing the sub-obligations (e,g. region constraints). Only code that is specifically aware of the new 'complete' code is affected		2021-12-18 19:07:14 -05:00
