Since commit 3469797d changed to build libdispatch for SourceKit with the
host compiler, we now require a clang with builtin `__builtin_add_overflow`.
Since Ubuntu 14 repositories have a clang that supports this update our
build instructions to use it.
Resolves [SR-8925](https://bugs.swift.org/browse/SR-8925).

Getting Started with Swift on Ubuntu 14.04
Upgrade Clang
You'll need to upgrade your clang compiler for C++14 support and create a symlink. The minimum required version of clang may change, and may not be available on Ubuntu 14.04 in the future.
sudo apt-get install clang-3.9
sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-3.9 100
sudo update-alternatives --install /usr/bin/clang++ clang++ /usr/bin/clang++-3.9 100
sudo update-alternatives --set clang /usr/bin/clang-3.9
sudo update-alternatives --set clang++ /usr/bin/clang++-3.9
Upgrade CMake
You'll need to upgrade your CMake toolchain to a supported version by building a local copy. The minimum required version of CMake may change, and may not be available on Ubuntu 14.04 in the future.
wget https://cmake.org/files/v3.5/cmake-3.5.2.tar.gz
tar xf cmake-3.5.2.tar.gz
cd cmake-3.5.2
./configure
make
sudo make install
sudo update-alternatives --install /usr/bin/cmake cmake /usr/local/bin/cmake 1 --force
cmake --version # This should print 3.5.2
