[Vectorizer] Make REDUC_xxx_EXPR tree codes produce a scalar result
PR tree-optimization/61114
* expr.c (expand_expr_real_2): For REDUC_{MIN,MAX,PLUS}_EXPR, add
extract_bit_field around optab result.
* fold-const.c (fold_unary_loc): For REDUC_{MIN,MAX,PLUS}_EXPR, produce
scalar not vector.
* tree-cfg.c (verify_gimple_assign_unary): Check result vs operand type
for REDUC_{MIN,MAX,PLUS}_EXPR.
* tree-vect-loop.c (vect_analyze_loop): Update comment.
(vect_create_epilog_for_reduction): For direct vector reduction, use
result of tree code directly without extract_bit_field.
* tree.def (REDUC_MAX_EXPR, REDUC_MIN_EXPR, REDUC_PLUS_EXPR): Update
comment.
