    MSVC Builds: Speed Up Release Builds
    
    Use the multiprocessor compilation (/MP) flag, which can help to cut down
    release build times by quite a bit.  This will emit a brief warning for
    debug builds, due to the use of /Gm, but the build will otherwise proceed
    normally.
    
    Also use the /d2Zi+ compiler flag for Visual Studio 2010 and later so that
    more useful information can be logged to the .pdb files for release builds,
    which will help debugging release binaries.
