This is a part of https://reviews.llvm.org/D95835. The design is based on MSan origin chains. An 4-byte origin is a hash of an origin chain. An origin chain is a pair of a stack hash id and a hash to its previous origin chain. 0 means no previous origin chains exist. We limit the length of a chain to be 16. With origin_history_size = 0, the limit is removed. The change does not have any test cases yet. The following change will be adding test cases when the APIs are used.
