Sergey Glukhov c7371c9e75 Bug#57477 SIGFPE when dividing a huge number a negative number ...

The problem is dividing by const value when
the result is out of supported range.
The fix:
-return LONGLONG_MIN if the result is out of supported range for DIV operator.
-return 0 if divisor is -1 for MOD operator.


mysql-test/r/func_math.result:
  test case
mysql-test/t/func_math.test:
  test case
sql/item_func.cc:
  -return LONGLONG_MIN if the result is out of supported range for DIV operator.
  -return 0 if divisor is -1 for MOD operator.
