This change appears to have broken several libc++ tests:
```
error: no matching constructor for initialization of 'std::vector<bool>'
note: candidate template ignored: constraints not satisfied [with _Range = std::ranges::subrange<cpp20_input_iterator<bool *>, sentinel_wrapper<cpp20_input_iterator<bool *>>> &]
note: because '_ContainerCompatibleRange<std::allocator<bool>, bool>' evaluated to false
```
Would it be possible to revert the change?
