Merge branch 'flatten-rules-into-productions'
...
This branch had diverged considerably, so merging it required changing a lot
of code.

Separate syntax rules into flat lists of symbols

This way, every ParseItem can be associated with a particular production
for its non-terminal. That lets us keep track of which productions are
involved in shift/reduce conflicts.

Store ParseItemSets as maps, w/ core items as keys
...
ParseItem no longer has a lookahead_sym field; it now represents
the 'core' of a parse item. The lookahead context is stored separately,
as a set per core item. This makes iterating, copying and merging item
sets more efficient, because before, the core items were repeated for each
different lookahead symbol.
Also, the memoization in sym_transitions(ParseItemSet) has been removed.
Maybe I'll add it back later.
