Snappy Team 7b82423c59 The output buffer in DecompressBranchless is never read from and the source buffers are never written. This allows us to defer any writes to the output buffer for an arbitrary amount of time as long as the writes all occur in the proper order. When a MemCopy64 would have normally occurred we save away the source address and length. Once we reach the location of the next write to the output buffer first perform the deferred copy. This gives time for the source address calculation and length to finish before the deferred copy. ...

This change gives 1.84% on CLX and 0.97% Milan.
