Rollup merge of #66013 - nnethercote:avoid-hashing-twice-in-get_query, r=Zoxc
Avoid hashing the key twice in `get_query()`.

For a single-threaded parallel compiler, this reduces instruction counts
across several benchmarks, by up to 2.8%.

The commit also adds documentation about `Sharded`'s use of `FxHasher`.
