Original issue's description:
> Avoid LSan false positives from CSSPathValue::emptyValue().
>
> LSan reports a leak on SVGComputedStyleTest.MiscStyleShouldCompareValue
> (with Oilpan), stemming from emptyValue()'s allocation of an
> SVGPathByteStream object. Introduce a local constructor function that
> explicitly keeps this sub-object from LSan's view -- it is owned by
> the emptyValue singleton and shouldn't be considered a leak.
