  * Results are returned though an array of capture indices, stored at
  * matches_param_. A null array specifies a failure to match. The match indices
  * [start_inclusive, end_exclusive] for capture group i are stored at positions
  * matches_param_[i * 2] and matches_param_[i * 2 + 1], respectively. Match
  * indices of -1 denote non-matched groups. Note that we store these indices
  * as a negative offset from the end of the string in registers_array_
  * during processing, and convert them to standard indexes when copying them
  * to matches_param_ on successful match.
