[libc++] Revert the part of my b82683b that affected <version>. This reverts part of commit b82683b2eb3601f6e8970861b94ad7b37393aa90. I hadn't intended to remove the `// -*- C++ -*-` comment line from `libcxx/include/version`, only from the generated tests. Thanks to Raul Tambre for the catch.

//
Update more file headers across all of the LLVM projects in the monorepo to reflect the new license. These used slightly different spellings that defeated my regular expressions. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351648

Implement feature test macros using a script. Summary: This patch implements all the feature test macros libc++ currently supports, as specified by the standard or cppreference prior to C++2a. The tests and `<version>` header are generated using a script. The script contains a table of each feature test macro, the headers it should be accessible from, and its values of each dialect of C++. When a new feature test macro is added or needed, the table should be updated and the script re-run.

[libc++][format][1/6] Reduce binary size. This removes the `format_args_t` from `<format>` and adjusts the type of the `format_args` for the `vformat_to` overloads. The `format_context` uses a `back_insert_iterator<string>` therefore the new `output_iterator` function uses a `string` as its temporary storage buffer. This isn't ideal. The next patches in this series will improve this. These improvements make it easy to also improve `format_to_n` and `formatted_size`. This addresses P2216 `6. Binary size`. P2216 `5.

Implement feature test macros using a script. Summary: This patch implements all the feature test macros libc++ currently supports, as specified by the standard or cppreference prior to C++2a. The tests and `<version>` header are generated using a script. The script contains a table of each feature test macro, the headers it should be accessible from, and its values of each dialect of C++. When a new feature test macro is added or needed, the table should be updated and the script re-run.

[libc++] Fix feature test macro for __cpp_lib_to_chars We would have been defining it in <utility> instead of <charconv>. For the time being, this doesn't change anything since we don't implement the feature test macro anyways. Also, as a fly-by, this removes obsolete feature test macro tests. There was a brief time back in the days when we wrote feature test macro tests manually. In particular, we had test files for __cpp_lib_to_chars and __cpp_lib_memory_resource. Since we now have a principled way of generating these tests with scripts, this commit removes the obsolete (and empty) tests for these two feature test macros.

That's because it is used only in `__visit_value_at`, which in turn is always used on variant specializations (that's in comparison operators). * https://wg21.link/P2162 Reviewed By: ldionne, #libc, Quuxplusone Differential Revision: https://reviews.llvm.org/D97394

It's the time to move the implementation of coroutine out of the experimental directory and the std::experimental namespace. This patch creates header <coroutine> with conformed implementation with C++ standard. To avoid breaking user's code too fast, the <experimental/coroutine> header is remained.

The `format_context` uses a `back_insert_iterator<string>` therefore the new `output_iterator` function uses a `string` as its temporary storage buffer. This isn't ideal. The next patches in this series will improve this. These improvements make it easy to also improve `format_to_n` and `formatted_size`. This addresses P2216 `6. Binary size`. P2216 `5.

[libc++] [P0887] Add newest feature-test macros; mark `type_identity` as implemented. `__cpp_lib_type_identity` was implemented way back in cf49ccd0 (Clang 8), probably before the feature-test macro had been settled on. `__cpp_lib_string_resize_and_overwrite` will be added by D113013 so I didn't add it here.

Implement feature test macros using a script. Summary: This patch implements all the feature test macros libc++ currently supports, as specified by the standard or cppreference prior to C++2a. The tests and `<version>` header are generated using a script. The script contains a table of each feature test macro, the headers it should be accessible from, and its values of each dialect of C++. When a new feature test macro is added or needed, the table should be updated and the script re-run.
