We plan to switch the Windows build machines to Visual Studio 2013 on the Firefox 35 train.

Some benefits from this change:
* No more linker OOM crashes. VS2013 includes a 64-bit toolchain for 32-bit builds, so the linker will no longer be limited to 4GB address space.
* The linker capacity opens the door for merging our binaries into libxul (like we do on the other platforms)
* More than 2x improvement in PGO build times
* Better language support
