re2: memory diet Cut unnecessary fields from Regexp and order to align better. Combine smallsub and sub into one field. Changes sizeof(Regexp) - a single node - from 104 to 40 bytes. Use sorted array as permanent representation of character class, avoiding the bloat of STL set<>. Combined with CL 1129043, cuts storage used by a typical RE2 object by about 60%.
