[PATCH] D45399: Split SectionPiece in its parts

More testing in an oldish xeon shows that almost half of the time in the getOffset method is because of one memory access, the one fetching OutputOff in

  return Pieces[It->second].OutputOff;

putting all the OutputOff in a single vector improves it.

Having the Hashes in their own vector has the additional nice property that we can free it.

I am still benchmarking it.
