…match. The `filter`, `exists_one` and `map` with a filter macros expand their predicate into the condition of `_?_:_`. When the predicate isn't a bool the type-checker reports `found no matching overload for '_?_:_' applied to ...'`, which points at an operator that doesn't appear in the expression. Report `expected type 'bool' but found '<type>'` at the condition instead, as is already done for the operands of `&&` and `||`. PiperOrigin-RevId: 1003153382
