* Standardize how analysis results/passes as printed with the print() virtual

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.
