    Reason for revert: Clusterfuzz found something.
    
    Original change's description:
    > [interpreter] Add bytecode for leading array spreads.
    > 
    > This CL improves the performance of creating [...a, b] or [...a].
    > If the array literal has a leading spread, this CL emits the bytecode
    > [CreateArrayFromIterable] to create the literal. CreateArrayFromIterable
    > is implemented by [IterableToListDefault] builtin to create the initial
    > array for the leading spread. IterableToListDefault has a fast path to
    > clone efficiently if the spread is an actual array.
    > 
    > The bytecode generated is now shorter. Bytecode generation is refactored
    > into to BuildCreateArrayLiteral, which allows VisitCallSuper to benefit
    > from this optimization also.
    > For now, turbofan also lowers the bytecode to the builtin.
    > 
    > The idiomatic use of [...a] to clone the array a now performs better
    > than a simple for-loop, but still does not match the performance of slice.
