MAJOR REWRITE. - stop passing Buf/BufEnd to every function (now member vars) - internalize things that used to be in a header file that no one else   included/needed. - Remove defunct BCR_TRACE lines - Standardize error handling with the PARSE_ERROR macro. - Integrate ConstantReader.cpp and InstructionReader.cpp and reorgnize   the definition order so that gcc has a chance at optimizing this module - Standardize case and style of method names. - Eliminate unneeded header files - Prepare for Type != Value (bug122) change by splitting Types into their   own data structures. - Implement the BytecodeHandler interface calls. - Provide default implementation of BytecodeHandler interface.
