Chandler Carruth 57b08b0944 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.

JF Bastien 1026ce6de4 [NFC] Always lock free test: add indirection
I have a big patch coming up, and this indirection is required to avoid hitting the following after my big change:

  error: empty struct has size 0 in C, size 1 in C++ [-Werror,-Wextern-c-compat]

Stephan T. Lavavej 04576cc060 [libcxx] [test] Improve MSVC portability.
test/support/msvc_stdlib_force_include.hpp
When testing MSVC's STL with C1XX, simulate a couple more compiler feature-test macros.

When testing MSVC's STL, simulate a few library feature-test macros.

test/std/atomics/atomics.lockfree/isalwayslockfree.pass.cpp
The vector_size attribute is a non-Standard extension that's supported by Clang and GCC,
but not C1XX. Therefore, guard this with `__has_attribute(vector_size)`.

Additionally, while these tests pass when MSVC's STL is compiled with Clang,
I don't consider this to be a supported scenario for our library,
so also guard this with defined(_LIBCPP_VERSION).

test/std/utilities/function.objects/func.not_fn/not_fn.pass.cpp
N4713 23.14.10 [func.not_fn]/1 depicts only `call_wrapper(call_wrapper&&) = default;`
and `call_wrapper(const call_wrapper&) = default;`. According to
15.8.2 [class.copy.assign]/2 and /4, this makes call_wrapper non-assignable.
Therefore, guard the assignability tests as libc++ specific.

Add a (void) cast to tolerate not_fn() being marked as nodiscard.

Fixes D41213.
