IMPALA-4498: crash in to_utc_timestamp/from_utc_timestamp
The bugs was that the functions did not check whether the conversion
pushed the value out of range. The fix is to use boost's validation
immediately to check the validity of the timestamp and catch any
exceptions thrown.
It would be preferable to avoid the exceptions, but Boost does not
provide a straightforward way to disable the exceptions or extract
potentially-invalid values from a date object.
Testing:
Added expression tests that exercise out-of-range cases. Also
added additional tests to confirm that date addition and subtraction
weren't affected by similar bugs.
