Oh.. I see what happened.  We used to have `LazyArchive` and `LazyObject` (two different kinds of lazy symbols) from http://reviews.llvm.org/D18814, but they were unified so now we are just left with `LazyObject`.  

I will instead propose we move ELF to `LazySymbol` which is more consistent with the other symbol types and more descriptive (IMHO).
