[dev.link] cmd/internal/obj: handle content-addressable symbols with relocations For content-addressable symbols with relocations, we build a content hash based on its content and relocations. Depending on the category of the referenced symbol, we choose different hash algorithms such that the hash is globally consistent. For now, we only support content-addressable symbols with relocations when the current package's import path is known, so that the symbol names are fully expanded. Otherwise, if the referenced symbol is a named symbol whose name is not fully expanded, the hash won't be globally consistent, and can cause erroneous collisions. This is fine for now, as the deduplication is just an optimization, not a requirement for correctness (until we get to type descriptors).
