<pre>Visual Studio 2017 15.8 adds opt-in support for parallelised building of custom
tools stages in a project:
<a href="https://blogs.msdn.microsoft.com/vcblog/2018/09/18/parallel-custom-build-tools-in-visual-studio-2017/">https://blogs.msdn.microsoft.com/vcblog/2018/09/18/parallel-custom-build-tools-in-visual-studio-2017/</a>
This will considerably help speed up llvm-tblgen builds if we can enable this
as soon as any necessary cmake changes have been made.</pre>
