3ec9a0a5cf We need to know the call sites each function hosts

198be22cec - Add "ResolvingCaller" to the CallSite record. This keeps track of which
function was finally able to resolve the function call.  Adding this allows
    the TD pass to actually work right!
  - Temporarily disable dead node pruning.  This will be reenabled soon.

3c579faece Added a first-class representation for each call site that can be
used in the DS graphs in DSGraph.h.  With that, the special-purpose
class BUDataStructure::CallSite is no longer needed here.

  the analyses themselves.

6aa0d62cb9 Add support for a top-down propagation pass.
Each DSGraph now keeps a list of pending callers that have not
been inlined into the function represented by that graph.
It also keeps a copy of the original call nodes before the BU pass
eliminates some of them.

f57b845547 * 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
