Attila Jeges updated IMPALA-7368:
---------------------------------
    Description: 
DATE values describe a particular year/month/day, in the form YYYY-­MM-­DD. For 
example, DATE '2013-­01-­01'. Date types do not have a time of day component. 
The range of values supported for the Date type is 0000-­01-­01 to 9999-­12-­31.

The initial DATE type support should incluide the following changes:
- new internal type
- text scanner/writer
- casting between DATE and other types
- codegen infrastructure for expression evaluation
- "IS [NOT] NULL" and "[NOT] IN" predicates
- common comparison operators 
- conditional functions
- infrastructure changes for builtin scalar functions.

These items are tightly coupled and it makes sense to implement them in one 
change-set.
