Review request for hive and John Sichi.
Changes
-------
Gut the changes to TypeProcFactory and the grammer, instead amend COALESCE and
UNION ALL to allow type widening.
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,
Syed
