The serialization of Construct was accidentally using the wrong hints for the receiver. Also, the recursion in ProcessCallOrConstruct was not quite right: for example, it overwrote the accumulator hints in each recursion. With this CL the Octane raytrace score for --concurrent-inlining is back to the default configuration's score.
