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.

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.

Add new RegionInfo pass.
...
The RegionInfo pass detects single entry single exit regions in a function,
where a region is defined as any subgraph that is connected to the remaining
graph at only two spots.
Furthermore an hierarchical region tree is built.
Use it by calling "opt -regions analyze" or "opt -view-regions".
