Bug 1275297 - Create Visual Studio project files by default on Windows; r=glandium Now that the VisualStudio backend will no-op if nothing has changed, it should be safe to always run this backend. On first run, backend generation takes ~3.5s on my machine. On subsequent run, it takes ~1.5s. Wall time for a no-op config.status is now ~15.7s. We could like make the Visual Studio backend faster by not writing so many project files. But this would require consolidating libraries in moz.build files. And that's out of scope for this change.
