> Does this depend on https://reviews.llvm.org/D41390?

I did it this way round, because I thought https://reviews.llvm.org/D41390 was the less controversial, and hence would be applied first. I wanted to add the `Discarded` flag and behaviour, without having to wait for discussion of the COMDAT to grind on.

The COMDAT support here does depend on the Discarded flag added in https://reviews.llvm.org/D41390, so I think the order does make sense.
