Here in `DLLFile`, we change the constructor to take a `SymbolTable&` instead, while for `ObjFile` above, we keep taking a `COFFLinkerContext&` parameter, and resolve `ctx.symtab` within the `ObjFile` constructor; 1) why the inconsistency, and 2) shouldn't we stop doing `ctx.symtab` here? Or is that a leftover that gets taken care of in one of the upcoming patches?
