Daniël de Kok 63fa55089d Use constant-time head lookups in StateC::{L,R} 
This change changes the type of left/right-arc collections from
vector[ArcC] to unordered_map[int, vector[Arc]], so that the arcs are
keyed by the head. This allows us to find all the left/right arcs for a
particular head in constant time in StateC::{L,R}.

Benchmarks with long docs (N is the number of text repetitions):
