    [builtins] Patch self-references in constants table · 6379e2a4
    jgruber authored
    During code generation, we generate self-references (i.e. references to
    the Code object currently being generated) as references to a temporary
    handle. When the final Code object has been allocated, the handle's
    location is fixed up and RelocInfo iteration fixes up all references
    embedded in the generated code.
    
    This adds support for this mechanism to the builtins constants table
    builder. CodeObject() is now a new handle pointing to a dedicated
    self-reference marker in order to distinguish between self-references
    and references to undefined. In Factory::NewCode, we patch up
    the constants table.
