* fold-const.cc (fold_vec_perm_cst): Set result's encoding to sel's
encoding, and set res_nelts_per_pattern to 2 if sel contains stepped
sequence but input vectors do not.
(test_nunits_min_2): New test Case 8.
(test_nunits_min_4): New tests Case 8 and Case 9.
gcc/testsuite/ChangeLog:
PR middle-end/111754
