Before this patch, we would fail to implicitly convert the result of predicates to bool, which means we'd potentially perform a copy or move construction of the boolean-testable, which isn't allowed. The same holds true for comparing iterators against sentinels, which is allowed to return a boolean-testable type. We already had tests aiming to ensure correct handling of these types, but they failed to provide appropriate coverage in several cases due to guaranteed RVO. This patch fixes the tests, adds tests for missing algorithms and views, and fixes the actual problems in the code. Fixes #69074
