9d3b4aab4b Make Where and NamedExpression macros easier to use
Summary:
`Where` can now be constructed in a `QUERY`, instead of requiring manual
addition to `Match`. For example:

    auto query = QUERY(MATCH(pattern), WHERE(expr), ...);

compared to:

    auto match = MATCH(pattern);
    match->where_ = WHERE(expr);
    auto query = QUERY(match, ...);

Similarly, `AS` can be used instead of `NEXPR` to create
`NamedExpressions` only with a name. This is meant to be used with
`RETURN` which will look at the previous `Expression` and store it
inside `NamedExpression`. For example:

    auto ret = RETURN(IDENT("n"), AS("n"),
                      PROPERTY_LOOKUP("n", prop), AS("prop_val"));

compared to:

    auto ret = RETURN(NEXPR("n", IDENT("n")),
                      NEXPR("prop_val", PROPERTY_LOOKUP("n", prop)));

68e94e64e4 Plan set operations
Summary:
Inline and remove GenProduce.
It doesn't do anything useful, so instantiating `Produce` can be done
inline.

Add dummy MakeCursor overrides for set operators so that the build passes.
