    Check published FunctionTemplateInfo is immutable · 1040aef3
    Nico Hartmann authored
    This CL generalized the previous check that a FunctionTemplateInfo
    instance is not changed after being instantiated to a check for
    immutability after being published. A FTI is considered published once
    it is instantiated (set in a SharedFunctionInfo) or set as an accessor
    on a JSObject. The published state is tracked in the flags field.
    TurboFan relies on this immutabilty for concurrent access.
    
    The immutability requirement was already met before this CL, but this
    change enforces this by adding necessary checks.
