Owen Anderson 8ac477ffb5 Begin adding static dependence information to passes, which will allow us to 
perform initialization without static constructors AND without explicit initialization
by the client.  For the moment, passes are required to initialize both their
(potential) dependencies and any passes they preserve.  I hope to be able to relax
the latter requirement in the future.

Still very much under development. Comments and fixes will be forthcoming.

(This commit includes some small tweaks to LiveIntervals & LoopInfo to support the splitter)
