[try-run] `-Znext-solver` caching #129025

lcnr · 2024-08-12T21:26:51Z

#128828 except that it enables -Znext-solver=coherence 😅

try-job: x86_64-fuchsia

doing so requires overwriting global cache entries and generally adds significant complexity to the solver. This is also only ever done for root goals, so it feels easier to wrap the `evaluate_canonical_goal` in an ordinary query if necessary.

this allows us to only sometimes disable the global cache.

this makes it easier to maintain and modify going forward. There may be a small performance cost as we now need to access the provisional cache *and* walk through the stack to detect cycles. However, the provisional cache should be mostly empty and the stack should only have a few elements so the performance impact is likely minimal. Given the complexity of the search graph maintainability trumps linear performance improvements.
