Return the bitwise inclusive or of all return values instead of the
last call's value. This lets you find out whether any of the calls
returned a non-zero value.
No functional change, as existing users either don't care for the
value, or pass non-zero abort_on_failure, which breaks the loop on the
first non-zero return value.
