Can we avoid introducing the #if flag?

DEFINE_STATIC_LOCAL(OwnPtrWillBePersistent<>, ...)

I don't think CPP is entirely avoidable, as we need to use a separate type for
Oilpan (FilterOperationsWrapper vs FilterOperations), so I think it makes sense
to have it like this.

+const FilterOperations& RenderStyle::initialFilter()
+{
+    DEFINE_STATIC_LOCAL(Persistent<FilterOperationsWrapper>, ops, (FilterOperationsWrapper::create()));
+    return ops->operations();
+}
+#endif

     return LayoutBoxExtent(NinePieceImage::computeOutset(image.outset().top(), borderTopWidth()),
