[libcxx] Implement locale.h to fix modules build Summary: Because `locale.h` isn't part of the libc++ modules the class definitions it provides are exported as part of `__locale` (since it happens to be build first). This breaks `<clocale>` which exports `std::lconv` without including `<__locale>`. This patch implements `locale.h` to fix this issue, it also adds support for testing libc++ with modules.

// -*- C++ -*-
[runtimes][NFC] Remove filenames at the top of the license notice We've stopped doing it in libc++ for a while now because these names would end up rotting as we move things around and copy/paste stuff. This cleans up all the existing files so as to stop the spreading as people copy-paste headers around.

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

#include <__config>
[libc++] Move the #error message for no localization to <locale.h> <locale.h> is lower level than <__locale>, so that's where we want the error to live for systems that don't provide localization support.

#if defined(_LIBCPP_HAS_NO_LOCALIZATION)
[libc++] Improve error messages for disabled modes We should not surface CMake-level options like LIBCXX_ENABLE_FILESYSTEM to our users, since they don't know what it means. Instead, use a slightly more general wording. Also, add an error in <ios> to improve the quality of errors for people trying to use <iostream> when localization is disabled.

[libc++] Move the #error message for no localization to <locale.h> <locale.h> is lower level than <__locale>, so that's where we want the error to live for systems that don't provide localization support.
