Michael Ho 37a73ae9f7 IMPALA-3350: Add some missing StringVal.is_null checks
Impala has a hardcoded limit of 1GB in size for StringVal.
If the length of the string exceeds 1GB, Impala will simply
mark the StringVal as NULL (i.e. is_null = true). It's important
that string functions or built-in UDFs check this field before
accessing the pointer or Impala may end up doing null pointer
access, leading to crashes.
