* unroll.c (precondition_loop_p): Likewise.
(approx_final_value): Function deleted and subsumed
  into loop_iterations.
(loop_find_equiv_value): New function.
(loop_iterations): Use loop_find_equiv_value to find increments
too large to be immediate constants.  Also use it to find terms
common to initial and final iteration values that can be removed.
