    [Courgette] Refactor: Add CourgetteFlow; improve courgette_tool.cc help text. · 8b91a4c9
    huangs authored
    High level flows in Courgette has messy error-handling code that's
    hard to read. This CL adds CourgetteFlow to absorb commonly used data
    and error-handling code, and improve readability of high-level logic.
    Additional changes:
    - Fix Courgette-disadj (debugging flow), which likely was broken by
      http://crrev.com/2793153003; Adjust() is called but AssemblyProgram
      did not annotate Labels.
    - Add BasicBuffer interface, implemented by RegionBuffer and (existing)
      BufferedFileReader.
    - PatchGeneratorX86_32::Transform(): Implemented TODO to instantiate
      "new" AssemblyProgram to reduce Courgette-gen peak memory.
    - courgette_tools.cc: Make help text more uniform.
