This function returns the "inclusive or" of its arguments: the Nth
bit is set in the result if, and only if, the Nth bit is set in at
least one of the arguments. If there are no arguments, the result
is zero, which is an identity element for this operation. If
`logior' is passed just one argument, it returns that argument.
