* tree-vect-patterns.c (vect_recog_sad_pattern): New function for SAD
pattern recognition.
(type_conversion_p): PROMOTION is true if it's a type promotion
conversion, and false otherwise. Return true if the given expression
is a type conversion one.
* tree-vectorizer.h: Adjust the number of patterns.
* tree.def: Add SAD_EXPR.
* optabs.def: Add sad_optab.
* cfgexpand.c (expand_debug_expr): Add SAD_EXPR case.
* expr.c (expand_expr_real_2): Likewise.
* gimple-pretty-print.c (dump_ternary_rhs): Likewise.
* gimple.c (get_gimple_rhs_num_ops): Likewise.
* optabs.c (optab_for_tree_code): Likewise.
* tree-cfg.c (estimate_operator_cost): Likewise.
* tree-ssa-operands.c (get_expr_operands): Likewise.
