This flies completely in the face of the development model pushed by the
LLVM leadership.  We've been told over and over, "follow trunk and keep
up to date."  I have in fact been moving us in that direction.  It's a
massive undertaking and it has taken years to get the pieces in place.

I feel like I'm being pulled in two directions: one group says work off
trunk and another says work off major releases.  Which is it?
