Review request for hive and John Sichi.
Changes
-------
After talking to jhsu about this, looks like the motivation for this is to
provide a way to coerce int literals into bigints for UDFs that expect
arguments of the same type. E.g. COALESCE(0, 1152921504606846976) will
currently fail. With this updated patch, COALESCE(0L, 1152921504606846976)
passes.
Summary
-------
Added a rule to the lexical grammar to allow BIGINT constants ending with 'L',
and a clause to the TypeCheckProcFactory to ensure it gets interpreted properly.
This addresses bug HIVE-872.

Testing
-------
TestCliDriver passes, previous behaviour was to accept bigint constants
specified without 'L', which is also preserved, so adding additional tests for
this case seems unnecessary.
Thanks,
