Commit e130dea92a8ab477685469df261e3ecc72593525 by fraser [RISCV] Add vector integer mul/mulh/div/rem ISel patterns There is no test coverage for the mulhs or mulhu patterns as I can't get the DAGCombiner to generate them for scalable vectors. There are a few places in that still need updating for that to work. I left the patterns in regardless as they are correct.
