2155505dcd Enabled Fortify for libruntime.a 
There is currently no code in libruntime.a that Fortify can protect so this
doesn't actually change the generated assembly. However, we may add code in the
future that Fortify can protect.

clang defines `_FORTIFY_SOURCE` by default so we need to undefine then redefine
it to avoid build errors.

798ef5e4dc Add libFuzzer support 
This adds support for fuzzing tree-sitter grammars with libFuzzer. This
currently only works on Linux because of linking issues on macOS. Breifly, the
AddressSanitizer library is dynamically linked into the fuzzer binary and
cannot be found at runtime if built with a compiler that wasn't provided by
Xcode(?). The runtime library is statically linked on Linux so this isn't a
problem.

686dc0997c Avoid introducing certain lexical conflicts during parse state merging 
The current pretty conservative approach is to avoid merging parse states which
would cause a pair tokens to co-exist for the first time in any parse state,
where the two tokens can start with the same character and at least one of the
tokens can contain a character which is part of the grammar's separators.

22c550c9d6 Discard tokens after error detection to find the best repair 
* Use GLR stack-splitting to try all numbers of tokens to
  discard until a repair is found.
* Check the validity of repairs by looking at the child trees,
  rather than the statically-computed 'in-progress symbols' list

This branch had diverged considerably, so merging it required changing a lot
of code.

9a198562e0 Treat parse conflicts as errors in grammar compilation 
For now, only reduce/reduce conflicts w/ no tie-breaking precedence
are treated as errors. The rest are dropped, because shift/reduce
conflicts are currently very common because we don't have a way
of specifying associativity along w/ precedence.

52daffb3f3 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.
