Subject: Delete VEC_INTERLEAVE_*_EXPR.

	* tree.def (VEC_INTERLEAVE_HIGH_EXPR, VEC_INTERLEAVE_LOW_EXPR): Remove.
	* gimple-pretty-print.c (dump_binary_rhs): Don't handle
	VEC_INTERLEAVE_HIGH_EXPR and VEC_INTERLEAVE_LOW_EXPR.
	* expr.c (expand_expr_real_2): Likewise.
	* tree-cfg.c (verify_gimple_assign_binary): Likewise.
	* cfgexpand.c (expand_debug_expr): Likewise.
	* tree-inline.c (estimate_operator_cost): Likewise.
	* tree-pretty-print.c (dump_generic_node): Likewise.
	* tree-vect-generic.c (expand_vector_operations_1): Likewise.
	* fold-const.c (fold_binary_loc): Likewise.
	* doc/generic.texi (VEC_INTERLEAVE_HIGH_EXPR,
	VEC_INTERLEAVE_LOW_EXPR): Remove documentation.
	* optabs.c (optab_for_tree_code): Don't handle
	VEC_INTERLEAVE_HIGH_EXPR and VEC_INTERLEAVE_LOW_EXPR.
	(expand_binop, init_optabs): Remove vec_interleave_high_optab
	and vec_interleave_low_optab.
	* genopinit.c (optabs): Likewise.
	* optabs.h (OTI_vec_interleave_high, OTI_vec_interleave_low): Remove.
	(vec_interleave_high_optab, vec_interleave_low_optab): Remove.
	* doc/md.texi (vec_interleave_high, vec_interleave_low): Remove
	documentation.
	* tree-vect-stmts.c (gen_perm_mask): Renamed to...
	(vect_gen_perm_mask): ... this.  No longer static.
	(perm_mask_for_reverse, vectorizable_load): Adjust callers.
	* tree-vectorizer.h (vect_gen_perm_mask): New prototype.
	* tree-vect-data-refs.c (vect_strided_store_supported): Don't try
	VEC_INTERLEAVE_*_EXPR, use can_vec_perm_p instead of
	can_vec_perm_for_code_p.
	(vect_permute_store_chain): Generate VEC_PERM_EXPR with interleaving
	masks instead of VEC_INTERLEAVE_HIGH_EXPR and VEC_INTERLEAVE_LOW_EXPR.
	* config/i386/i386.c (expand_vec_perm_interleave2): If
	expand_vec_perm_interleave3 would handle it, return false.
	(expand_vec_perm_broadcast_1): Don't use vec_interleave_*_optab.
