17bc3dfaf7 Add a benchmark command 
This command measures the speed of parsing each grammar's examples.
It also uses each grammar to parse all of the *other* grammars' examples
in order to measure error recovery performance with fairly large files.

535879a2bd Represent byte, char and tree counts as 32 bit numbers 
The parser spends the majority of its time allocating and freeing trees and stack nodes.
Also, the memory footprint of the AST is a significant concern when using tree-sitter
with large files. This library is already unlikely to work very well with source files
larger than 4GB, so representing rows, columns, byte lengths and child indices as
unsigned 32 bit integers seems like the right choice.

38c144b4a3 Refine logic for deciding when tokens need to be re-lexed 
* While generating the lex table, note which tokens can match the
  same string. A token needs to be relexed when it has possible
  homonyms in the current state.
* Also note which tokens can match substrings of each other tokens.
  A token needs to be relexed when there are viable tokens that
  could match longer strings in the current state and the next
  token has been edited.
* Remove the logic for marking tokens as fragile on creation.
* Store the reusability/non-reusability of symbols off of individual
  actions and onto the entire entry for the state & symbol.

1e353381ff Don't create error node in lexer unless token is completely invalid 
Before, any syntax error would cause the lexer to create an error
leaf node. This could happen even with a valid input, if the parse
stack had split and one particular version of the parse stack
failed to parse.

Now, an error leaf node is only created when the lexer cannot understand
part of the input stream at all. When a normal syntax error occurs,
the lexer just returns a token that is outside of the expected token
set, and the parser handles the unexpected token.
