Joe Loser	d2baefae68	[libc++] Replace _LIBCPP_HAS_NO_CONCEPTS with _LIBCPP_STD_VER > 17. NFCI. ... All supported compilers that support C++20 now support concepts. So, remove `_LIB_LIBCPP_HAS_NO_CONCEPTS` in favor of `_LIBCPP_STD_VER > 17`. Similarly in the tests, remove `// UNSUPPORTED: libcpp-no-concepts`.

Arthur O'Dwyer	2a04decc4a	[libc++] [test] Simplify sentinel_wrapper and sized_sentinel. ... Remove `s.base()`; every test that wants to get the base of a "test sentinel" should use the ADL `base(s)` from now on. Differential Revision: https://reviews.llvm.org/D115766	2021-12-16 12:02:58 -05:00
Joe Loser	c16b13ebf9	[libc++] Implement P1989R2: range constructor for string_view ... Implement P1989R2 which adds a range constructor for `string_view`. Adjust `operator/=` in `path` to avoid atomic constraints caching issue getting provoked from this PR. Add defaulted template argument to `string_view`'s "sufficient overloads" to avoid mangling issues in `clang-cl` builds. It is a MSVC mangling bug that this works around.
