INSERT reports error.

## Bug Report

Please answer these questions before submitting your issue. Thanks!

### 1. Minimal reproduce step (Required)
```sql
CREATE TABLE t0(c0 DECIMAL UNSIGNED ZEROFILL , c1 CHAR DEFAULT '{' , c2 FLOAT UNSIGNED AS (c0) VIRTUAL NOT NULL UNIQUE ) ;
INSERT IGNORE INTO t0(c1, c0) VALUES ('3', NULL), ('&', -679917749);
INSERT IGNORE INTO t0(c1, c0) VALUES ('2', -1665002185) ON DUPLICATE KEY UPDATE c0=t0.c1;
```

### 2. What did you expect to see? (Required)

Statements execute successfully.

### 3. What did you see instead (Required)

```sql
mysql> INSERT IGNORE INTO t0(c1, c0) VALUES ('2', -1665002185) ON DUPLICATE KEY UPDATE c0=t0.c1;
ERROR 8141 (HY000): assertion failed: key: 748000000000006ba45f69800000000000000100038000000000000001, assertion: Exist, start_ts: 452029336601493507, existing start ts: 0, existing commit ts: 0
```
Also, when I SELECT contents in t0, MySQL and TiDB return different results.
In MySQL:
```sql
+------------+------+----+
| c0 | c1 | c2 |
+------------+------+----+
| 0000000003 | 3 | 3 |
+------------+------+----+
```
In TiDB:
```sql
mysql> select * from t0;
+------+------+----+
| c0 | c1 | c2 |
+------+------+----+
| NULL | 3 | 0 |
+------+------+----+
1 row in set (0.00 sec)

```

### 4. What is your TiDB version? (Required)
