PR111648: Fix wrong code-gen due to incorrect VEC_PERM_EXPR folding.
gcc/ChangeLog:
PR tree-optimization/111648
* fold-const.cc (valid_mask_for_fold_vec_perm_cst_p): If a1
chooses base element from arg, ensure that it's a natural stepped
sequence.
(build_vec_cst_rand): New param natural_stepped and use it to
construct a naturally stepped sequence.
(test_nunits_min_2): Add new unit tests Case 6 and Case 7.
