Updated patch that adds option to serialize core analysis cache as string. Possible values of :dump-core are :raw, :string, :none. Old true/false values supported for backward compatibility.
As for default, current patch uses :raw, but I think it makes more sense to use :string. Saving extra few mb of final js is quite good. I think most devs won't go deep into figuring out why js is big and just leave it as it is. Additional one-time parsing performance hit :string introduces acceptable: when :string is used, page loads in 1s while with :raw the time is ~800ms.
