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

_LIBCPP_BEGIN_NAMESPACE_STD
[libc++] Use the using_if_exists attribute when provided As discussed on cfe-dev [1], use the using_if_exists Clang attribute when the compiler supports it. This makes it easier to port libc++ on top of new platforms that don't fully support the C Standard library. Previously, libc++ would fail to build when trying to import a missing declaration in a <cXXXX> header. With the attribute, the declaration will simply not be imported into namespace std, and hence it won't be available for libc++ to use. In many cases, the declarations were *not* actually required for libc++ to work (they were only surfaced for users to use them as std::XXXX), so not importing them into namespace std is acceptable. The same thing could be achieved by conscious usage of `#ifdef` along with platform detection, however that quickly creates a maintenance problem as libc++ is ported to new platforms. Furthermore, this problem is exacerbated when mixed with vendor internal-only platforms, which can lead to difficulties maintaining a downstream fork of the library. For the time being, we only use the using_if_exists attribute when it is supported. At some point in the future, we will start removing #ifdef paths that are unnecessary when the attribute is supported, and folks who need those #ifdef paths will be required to use a compiler that supports the attribute.
