Fixes https://github.com/llvm/llvm-project/issues/50142, a miss of
further vectorization, where we can only achieve zext (xor (any_true),
-1).
Now in test case simd-setcc-reductions, it's converted to all_true.
Also fixes https://github.com/llvm/llvm-project/issues/145177, which is
all_true (setcc x, 0, eq) -> not any_true
any_true (setcc x, 0, ne) -> any_true
all_true (setcc x, 0, ne) -> all_true
