Add the fact that we anticipate switching to use (some subset of) C++11

after the 3.4 release to the release notes. See the *lengthy* llvmdev
and cfe-dev threads on this subject. There will be more emails,
discussion and announcements, but I want to make noise in as many places
as I can to get everyone's concerns voiced and understood.

@ -41,6 +41,16 @@ Non-comprehensive list of changes in this release
functionality, or simply have a lot to talk about), see the `NOTE` below
for adding a new subsection.
* This is expected to be the last release of LLVM which compiles using a C++98
toolchain. We expect to start using some C++11 features in LLVM and other
sub-projects starting after this release. That said, we are committed to
supporting a reasonable set of modern C++ toolchains as the host compiler on
all of the platforms. This will at least include Visual Studio 2012 on
Windows, and Clang 3.1 or GCC 4.7.x on Mac and Linux. The final set of
compilers (and the C++11 features they support) is not set in stone, but we
wanted users of LLVM to have a heads up that the next release will involve
a substantial change in the host toolchain requirements.
* The regression tests now fail if any command in a pipe fails. To disable it in
a directory, just add ``config.pipefail = False`` to its ``lit.local.cfg``.
See :doc:`Lit <CommandGuide/lit>` for the details.
