bede31ff3a Be more careful handling PHI nodes, which might be of potentially high degree. 
This reduces the time to verify a function from eon with a large number of
large PHI nodes from 22996s (6.38 hours) to 10.5499s

bfa964699f As it turns out, things will be simpler than I first expected. We no longer 
need any exception handling intrinsics beyond llvm.unwind. (yaay)

101d40060c rethrow is really the language independent primitive here. "throw" can be written 
in terms of it and llvm.exc.setcurrent.

verifier even if the module was not well formed.

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
