Fix hang in where-clause suggestion with `predicate_can_apply`
Using `predicate_may_hold` during error reporting causes an evaluation overflow, which (because we use `evaluate_obligation_no_overflow`) then causes the predicate to need to be re-evaluated locally, which results in a hang.
... but since the "add a where clause" suggestion is best-effort, just throw any overflow errors. No need for 100% accuracy.
r? `@lcnr` who has been thinking about overflows... Let me know if you want more context about this issue, and as always, feel free to reassign.
