revset: wrap arguments of 'or' by 'list' node

This makes the number of 'or' arguments deterministic so we can attach
additional ordering flag to all operator nodes. See the next patch.

We rewrite the tree immediately after chained 'or' operations are flattened
by simplifyinfixops(), so we don't need to care if arguments are stored in
x[1] or x[1:].
