Rollup merge of #45263 - Manishearth:hashmap-clean, r=bluss
Do some cleanups for hashmaps @mystor noticed some things whilst reading through the hashmap RawTable code. Firstly, in RawTable we deal with this hash_offset value that is the offset of the list of hashes from the buffer start. This is always zero, and this isn't consistently used (which means that we would have bugs if we set it to something else). We should just remove this since it doesn't help us at all. Secondly, the probing length tag is not copied when cloning a raw table. This is minor and basically means we do a bit more work than we need on further inserts on a cloned hashmap. r? @Gankro
