Hi Sjoerd,

On looking at some IR generated from C, the multiplications were performed at i32 and then sext to i64. So I've now added those patterns to MatchParallelMACSequences. This has required an interface change to AddMACCandidiate because of the need to look through the sext to get to the mul.
