Fix conflict reporting for shift/reduce conflicts w/ multiple reductions
...
We were failing to rule out shift actions with lower precedence.

Mark reductions as fragile based on their final properties
...
We previously maintained a set of individual productions that were
involved in conflicts, but that was subtly incorrect because
we don't compare productions themselves when comparing parse items;
we only compare the parse items properties that could affect the
final reduce actions.

Improve heuristics for pruning parse versions based on errors
...
* Rewrite the error cost comparison in terms of explicit, discrete
conditions.
* Allow merging versions have different error costs.
* Store the depth of each stack version since the last error. Use this
state to prevent incorrect merging.
* Sort the stack versions in order of preference and put a hard limit on
the version count.
