Use the /MP option so that each project can build multiple sources in
parallel, which can cut down release build times by quite a bit. This will
cause a brief warning for debug builds due to their use of /Gm, and builds
would otherwise proceed as they did before.
Unfortunately Visual Studio 2008 is too old to support the /d2Zi+ flag, so
we can't make a better debug situation for it at the moment.
