Change subject: IMPALA-3884: Support TYPE_TIMESTAMP for HashTableCtx::CodegenAssignNullValue() ...................................................................... IMPALA-3884: Support TYPE_TIMESTAMP for HashTableCtx::CodegenAssignNullValue() This change implements support for TYPE_TIMESTAMP for HashTableCtx::CodegenAssignNullValue(). TimestampValue itself is 16 bytes in size. To match RawValue::Write() in the interpreted path, CodegenAssignNullValue() emits code to assign HashUtil::FNV_SEED to both the upper and lower 64-bit of the destination value. This change also fixes the handling of 128-bit Decimal16Value in CodegenAssignNullValue() so the emitted code matches the behavior of the interpreted path.
