This is a very small performance win that I noticed while trying to optimize
FrameStreamSendMetadata.This change calculates the
mockHeaderLengthinFrameStreamSendMetadataby hand instead of going through the Serializer. This now allows the Swift optimizer to optimize this path entirely away. Saves about 10 megacycles.
