This functions is amongst the most called in JS, so it's important to
make it speedy.
- Bugfix: if 'originalValue' is falsy, the result was never cached. This
in particular affected the minRange of archers, which is 0. It's a large
optimisation on combatDemoHuge, but the effect elsewhere is less likely
to be noticeable.
- Don't go through the helper to get the player Entity ID, in this case
it's slower.
- Concat is slower than Flat() in this case according to my profiling.
- Some micro-optimisation by strict equality.
