Implement interleave via permutation.
* expr.c (expand_expr_real_2) [VEC_EXTRACT_EVEN_EXPR]: Use binop.
[VEC_EXTRACT_ODD_EXPR, VEC_INTERLEAVE_HIGH_EXPR]: Likewise.
[VEC_INTERLEAVE_LOW_EXPR]: Likewise.
* optabs.c (expand_binop): Implement vec_interleave_high_optab,
vec_interleave_low_optab, vec_extract_even_optab,
vec_extract_odd_optab with expand_vec_perm.
(can_vec_perm_for_code_p): New.
* optabs.h: Update.
* tree-vect-data-refs.c (vect_strided_store_supported): Allow for
fallback via can_vec_perm_for_code_p.
(vect_strided_load_supported): Likewise.
* tree-vect-generic.c (expand_vector_operations_1): Never lower
VEC_INTERLEAVE_HIGH_EXPR, VEC_INTERLEAVE_LOW_EXPR,
VEC_EXTRACT_EVEN_EXPR, VEC_EXTRACT_ODD_EXPR.
