80f856cef5 Maintain a total node count on every tree 
This simplifies (and fixes bugs in) the parse stack's tracking of its
total node count since the last error, which is needed for error
recovery.

e59558c83b Allow stack versions to be temporarily paused 
This way, when detecting an error, we can defer the decision about
whether to bail or recover until all stack versions are processed.

52087de4f0 Remove the concept of fragile reductions 
They were a vestige of when Tree-sitter did sentential form-based
incremental parsing (as opposed to simply state matching). This was
elegant but not compatible with GLR as far as I could tell.

bc192d95ca Build fuzzer in 'halt' and 'recover' modes 
Build each language fuzzer in two modes (halt_on_error=true and
halt_on_error=false) and use different timeouts for each fuzzer.

Also merge the run-fuzzer and reproduce scripts so they use identical
values of ASAN_OPTIONS/UBSAN_OPTIONS/etc0

493db39363 Never move the start rule of a grammar into the lexical grammar 
This preserves a useful invariant that the root node of the AST is never
a token.
