    Added some minor pretty printing in the OfflineASM.
    Also added infrastruture for adding multiple types of comments and
    annotations with the ability to enable/disable them in the generated
    output as desired.
    
    * GNUmakefile.list.am: add new file config.rb.
    * llint/LLIntOfflineAsmConfig.h:
      Added OFFLINE_ASM_BEGIN, OFFLINE_ASM_END, and OFFLINE_ASM_LOCAL_LABEL macros.
      This will allow us to redefine these for other backends later.
    * llint/LowLevelInterpreter32_64.asm:
      Add a small example of instruction annotations for now.
    * llint/LowLevelInterpreter64.asm:
      Add a small example of instruction annotations for now.
    * offlineasm/armv7.rb: Added handling of annotations.
    * offlineasm/asm.rb:
      Added machinery to dump the new comments and annotations.
      Also added some indentations to make the output a little prettier.
    * offlineasm/ast.rb: Added annotation field in class Instruction.
    * offlineasm/backends.rb:
    * offlineasm/config.rb: Added.
      Currently only contains commenting options.  This file is meant to be
      a centralized place for build config values much like config.h for
      JavaScriptCore.
    * offlineasm/generate_offset_extractor.rb:
    * offlineasm/instructions.rb:
    * offlineasm/offsets.rb:
    * offlineasm/opt.rb:
    * offlineasm/parser.rb: Parse and record annotations.
    * offlineasm/registers.rb:
    * offlineasm/self_hash.rb:
    * offlineasm/settings.rb:
    * offlineasm/transform.rb:
    * offlineasm/x86.rb: Added handling of annotations.
