[dev.link] cmd/internal/goobj2, cmd/link: change data type for local object/index representation Use uint32 consistently for local index (this is what the object file uses). Use a index, instead of a pointer, to refer to the object file. This reduces memory usage and GC work. This reduces some allocations.
