* Implement stuff so that code can declare that they only depend on the CFG of
a function, not on anything else. This speeds up GCCAS a lot.

methods
* Eliminate AnalysisID: Now it is just a typedef for const PassInfo*
* Simplify how AnalysisID's are initialized
* Eliminate Analysis/Writer.cpp/.h: incorporate printing functionality into
the analyses themselves.

Now for llc, gccas, analyze, opt, etc you can specify the -time-passes
command line option that outputs a timing summary report that indicates
how long each pass takes to execute.

- 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

* Implement pass memory freeing after the pass is unused
* Expose PassManager typedef in Pass.h instead of PassManager.h

creates analysis results for passes that need them. MethodPass's never
have to worry about being invoked on external methods.
