Thanks @grimar and @ruiu. I have updated the diff to incorporate your suggestions and fixes. I've also incorporated some of @grimar's test ideas from https://reviews.llvm.org/D30901, since they were useful. I hope you don't mind me shamelessly copying!

I haven't yet tried to compare performance. @ruiu, what do you use to measure LLD's performance?
