    Collect type feedback in separate pass and store it in AST · 6fda4e4c
    rossberg@chromium.org authored
    Notes:
    
    - For now, just adds the missing type info fields to the AST nodes directly.
      I'd like to factor that out more nicely in a follow-up CL.
    
    - All type feedback now is uniformly collected through AST nodes'
      RecordTypeFeedback functions. At some point, this logic should be moved
      out of ast.cc.
    
    - The typing pass currently simulates the exact same conditions under
      which feedback was collected in Hydrogen before. That also should be
      made more generic in the future.
    
    - Type information itself is unchanged. Making it more regular is
      yet more future work.
    
    Some additional cleanups:
    
    - Lifted out nested class ObjectLiteral::Property, to enable forward declaration.
    - Moved around some auxiliary enums.
