        webkit-patch land should not build and test by default
        https://bugs.webkit.org/show_bug.cgi?id=33631

        Reverse the sense of --no-build and --no-test to be --build and --test.
        Also, decoupled the build and test options so you can test without
        building.

        (Patch manngled by Adam Barth.  All bugs are his fault.)
