revset: fix order of nested '_(|int|hex)list' expression (BC)
This fixes the order of 'x & (y + z)' where 'y' and 'z' are trivial, and the
other uses of _list()-family functions. The original functions are renamed to
'_ordered(|int|hex)list' to say clearly that they do not follow the subset
ordering.
