* Eliminate dead code that should have been removed in last revision

* Convert main constant propogation pass to be worklist driven instead of
iterative.
* -constprop pass no longer "constant propogates" terminator instructions

* Remove dead PHI case (which could not work due to getNumOperands rather than
getNumIncomingValues. This really belongs in InstCombine, anyway so we'll
move it there.

* Rename MethodPass class to FunctionPass
...
- Rename runOnMethod to runOnFunction
* Transform getAnalysisUsageInfo into getAnalysisUsage
- Method is now const
- It now takes one AnalysisUsage object to fill in instead of 3 vectors
to fill in
- Pass's now specify which other passes they _preserve_ not which ones
they modify (be conservative!)
- A pass can specify that it preserves all analyses (because it never
modifies the underlying program)
* s/Method/Function/g in other random places as well

Operands are maintained as a vector<Use> in the User class, and operator

a virtual function call.

of returning null!
