In the CM.  For each #specialists, compute min-luxuries.  Then if we
know we have n specialists, we know we need to produce a certain number
of luxuries (namely, min_{n' >= n} min-luxuries) no matter what; which
implies we need a certain function of lux+trade.  We can check that
against the heuristic.  The calculation isn't trivial devtime-wise but
it's very cheap runtime-wise: at the outset (in start_search),
pcity->size calls to city_luxury_need, and then it's just a constant-time
lookup per internal node.

This would speed up cities that are almost in disorder or that need to
celebrate.  I had this idea ages ago but never got around to
implementing it.
