Auto merge of #25921 - eddyb:inline-calculate-offsets, r=Aatch

The `HashMap` and `HashSet` iterators use `RawTable::first_bucket_raw` which is generic and will get inlined cross-crate.
However, `first_bucket_raw` calls `calculate_offsets` and the call doesn't get inlined, despite being a simple function.
This missing `#[inline]` results in `hash_table::calculate_offsets` showing up at the top of a callgrind profile with 3 million calls (for the testcase in #25916).
