This was a late-breaking (Oct 2021) change to C++20.
The only thing missing from this patch is that we're supposed
to bump the feature-test macro from
#define __cpp_lib_ranges 202106L
to
#define __cpp_lib_ranges 202110L
but we can't do that because we don't implement all of 202106 Ranges yet.

[libc++][NFC] Refactor the std::reverse_view tests
...
Mostly, remove the global assumption that all ranges have size 8.
I should have called this out during the initial review.

[libc++] Remove Lit annotations for unsupported GCC versions from the test suite
...
Since we officially don't support several older compilers now, we can
drop a lot of the markup in the test suite. This helps keep the test
suite simple and makes sure that UNSUPPORTED annotations don't rot.
This is the first patch of a series that will remove annotations for
compilers that are now unsupported.
