I'm enclosing my patch for reforming MCSectionCOFF to match the
implementation strategy of the other two MCSection classes. You may find
it useful as a starting point. It seems to be complete and correct, and
worked for what I tried with it, but I didn't find time to test it fully
(e.g., by bootstrapping clang under Cygwin).
