left() function fails to handle large negative integers correctly

[Phasheng]

Describe the bug
I discovered that left() function incorrectly processes large negative integers below INT_MIN instead of throwing error.

How are you accessing AGE (Command line, driver, etc.)?

• Command line

What is the command that caused the error?
When a negative integer bigger than INT_MIN is used as the length of left() function, an error will be caused:

SELECT * FROM cypher('test_graph', $$
RETURN LEFT('abcdef', -2147483648) AS ref0
$$) AS (ref0 agtype);

ERROR:  left() negative values are not supported for length

However, when executing query with large negative integer below -2147483648, the original text will be returned:

SELECT * FROM cypher('test_graph', $$
RETURN LEFT('abcdef', -2147483649) AS ref0, -2147483649 < 0 as ref1
$$) AS (ref0 agtype, ref1 agtype);

   ref0   | ref1 
----------+------
 "abcdef" | true

Expected behavior
Both queries above should fail with an error.

Environment:

• Latest in Docker hub
