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.
