Don't treat reused nodes as if they are error terms when merging errors.

Add badness penalty for forced reductions at end of input.

Fix several infinite loops around forced reductions.

Don't move error nodes out of reduces.

### New features

Add a `Parser.withProps` method for extending a parser with new node props.
