Dan Gohman 14fe8cf238 Consistently use AliasAnalysis::UnknownSize instead of hardcoding ~0u.

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.

Dan Gohman fb83b043eb Revert r111058, the lint check for indirectbr successors that aren't
address-taken. This can occur normally, if the code which took the
address got DCEd.

Owen Anderson 755aceb5d0 Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static
ID member as the sole unique type identifier.  Clean up APIs related to this change.
