Using -mllvm options was a nice reduction in the number of changes required in different tools, which was helpful to reduce the size of the initial PR. However, I think there is agreement now that proper options are required. Note that we don't have to update all the LLD ports at once. We can add DTLTO support to the different LLD ports incrementally. Perhaps we can start with just the ELF LLD port (chosen as it is the LLD port I'm most familiar with)?
