dfa: shrink constraints from 4 bits to 3 * lib/dfa.c (newline_constraint, letter_constraint) (other_constraint, prev_newline_dependent) (prev_letter_dependent, NO_CONSTRAINT, BEGLINE_CONSTRAINT) (ENDLINE_CONSTRAINT, BEGWORD_CONSTRAINT, ENDWORD_CONSTRAINT) (LIMWORD_CONSTRAINT, NOTLIMWORD_CONSTRAINT): Constraints need only 3 bits, not 4. Using smaller integers shrinks the code a bit and makes grep a tad faster on x86-64.
