(The large gain of the first STC was probably a fluke, and this result
is more reasonable!)

After shared correction history, Viz suggested we try sharing other
histories, especially `pawnHistory`. As far as we're aware, sharing
history besides correction history (like Caissa does) is novel. The
implementation follows the same pattern as shared correction history –
the size of the history table is scaled with
`next_power_of_two(threadsInNumaNode)` and the entry is prefetched in
`do_move`.

A bit of refactoring was done to accommodate this new history. Note that
we prefetch `&history->pawn_entry(*this)[pc][to]` rather than
`&history->pawn_entry(*this)` because unlike the other entries, each
entry contains multiple cache lines.
