Introduce partitioned unordered maps:

Browse Source 
This commit implements partitioned unordered maps and makes it possible
to traverse such a map in parallel, allowing for more efficient use of
CPU resources.

The `CachedSLEs`, `TaggedCache`, and `KeyCache` classes make use of the
new functionality, which should improve performance.
