PR tree-optimization/71261
* tree-vect-patterns.c (check_bool_pattern): Gather a hash-set
of stmts successfully put in the bool pattern. Remove
single-use restriction.
(adjust_bool_pattern_cast): Add cast at the use site via the
pattern def sequence.
(adjust_bool_pattern): Remove recursion, maintain a hash-map
of patterned defs. Use the pattern def seqence instead of
multiple independent patterns.
(sort_after_uid): New qsort compare function.
(adjust_bool_stmts): New function to process stmts in the bool
pattern in IL order.
(vect_recog_bool_pattern): Adjust.
* tree-if-conv.c (ifcvt_split_def_stmt): Remove.
(ifcvt_walk_pattern_tree): Likewise.
(stmt_is_root_of_bool_pattern): Likewise.
(ifcvt_repair_bool_pattern): Likewise.
(tree_if_conversion): Do not call ifcvt_repair_bool_pattern.
* gcc.dg/torture/vect-bool-1.c: New testcase.
