149376dee5 - Change Function's so that their argument list is populated when they are 
constructed.  Before, external functions would have an empty argument list,
    now a Function ALWAYS has a populated argument list.

bf3a099a62 Updates to work with recent Statistic's changes: 
* Renamed StatisticReporter.h/cpp to Statistic.h/cpp
    * Broke constructor to take two const char * arguments instead of one, so
      that indendation can be taken care of automatically.
    * Sort the list by pass name when printing
    * Make sure to print all statistics as a group, instead of randomly when
      the statistics dtors are called.
    * Updated ProgrammersManual with new semantics.

bedbd6bc16 - Cleanup break-crit-edges pass by making SplitCriticalEdge a member method.

have to support the cast instruction, so the function is renamed to getCast.

a13a2dac7e Cleanup ConstantExpr handling: 
* Correctly delete TypeHandles in AsmParser.  In addition to not leaking
   memory, this prevents a bug that could have occurred when a type got
   resolved that the constexpr was using
 * Check for errors in the AsmParser instead of hitting assertion failures
   deep in the code
 * Simplify the interface to the ConstantExpr class, removing unneccesary
   parameters to the ::get* methods.
 * Rename the 'getelementptr' version of ConstantExpr::get to
   ConstantExpr::getGetElementPtr

96a0dfa33e * 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.
