--------------------------------------------------------------------

Modified the grammar as pointed out. I moved ORDER BY and LIMIT to hinted_select_node. However,
hinted_select_node has to refer to hinted_set_select_node, but not through using select_node.
There are many more tests failing than before I made the modifications. Parameter count is
one thing. Checking aggregate and sequence are other issues related to context which could
be wrong too. This can potentially un-stablize Phoenix. The grammar change is not critical
for UNION ALL. I would request use Jira-1758 to track the grammar changes when we have better
thought of the consequences of grammar changes and what it really gains. Thanks. [~jamestaylor]
