Description:
The manual (6.3.6.1 Bit Functions) says that "^"(XOR) and ">>"(bit shift) return *unsigned* 64 bit value but it seems that they still return *signed* 64 bit value in some occasion.

How to repeat:
Following two sqls are typical ones:

mysql> SELECT -1>>0;
+-------+
| -1>>0 |
+-------+
|    -1 |
+-------+

mysql> SELECT -1^1;
+------+
| -1^1 |
+------+
|   -2 |
+------+
