bors 931aa27922 Auto merge of #80246 - matthewjasper:projection-cycle-caching, r=Mark-Simulacrum ... Prevent caching normalization results with a cycle When normalizing a projection which results in a cycle, we would cache the result of `project_type` without the nested obligations (because they're not needed for inference). This would result in the nested obligations only being handled once in fulfill, which would avoid the cycle error. `get_paranoid_cache_value_obligation` used to add an obligation that resulted in a cycle in this case previously, but was removed by #73905. This PR makes the projection cache not cache the value of a projection if it was ever normalized in a cycle (except in a snapshot that's rolled back). Fixes #79714. r? `@nikomatsakis`		2020-12-26 00:11:30 +00:00
