Arthur O'Dwyer 93e7f35ac3 [libc++] [NFC] Normalize some `#ifndef _LIBCPP_HAS_NO_CONCEPTS`. 2022-02-02 11:02:56 -05:00
Arthur O'Dwyer 2eb2ff2a02 [libc++] Merge _LIBCPP_HAS_NO_RANGES into _LIBCPP_HAS_NO_CONCEPTS. NFC.
The macro that opts out of `std::ranges::` functionality is called
`_LIBCPP_HAS_NO_INCOMPLETE_RANGES`, and is unrelated to this macro
which is specifically about _compiler_ support for the _syntax_.

The only non-mechanical diff here is in `<__config>`.

Konstantin Varlamov 8d23b7420c [libc++][ranges] Implement `uninitialized_copy{,_n}` and `uninitialized_move{,_n}`.
Also implement `in_out_result` which is a prerequisite.
