    Description

      This scalar query respects unsigned_flag difference for 18446744073709551615 and -1, goes through val_decimal() and correctly returns 0:

      SELECT 18446744073709551615 IN (18446744073709551614,-1);


      +---------------------------------------------------+
      		 
      | 18446744073709551615 IN (18446744073709551614,-1) |
      		 
      +---------------------------------------------------+
      		 
      |                                                 0 |
      		 
      +---------------------------------------------------+

      A similar query with ROW() erroneously returns 1:

      SELECT (18446744073709551615,0) IN ((18446744073709551614,0),(-1,0));


      +---------------------------------------------------------------+
      		 
      | (18446744073709551615,0) IN ((18446744073709551614,0),(-1,0)) |
      		 
      +---------------------------------------------------------------+
      		 
      |                                                             1 |
      		 
      +---------------------------------------------------------------+

      It ignores unsigned_flag, goes through val_int() and treats 18446744073709551615 and -1 as same values.

      This scalar query correctly returns an error:

      SELECT 1=POINT(1,1);


      ERROR 4078 (HY000): Illegal parameter data types int and geometry for operation '='

      A similar ROW query erroneously returns a result with a warning:

      SELECT (1,0) IN ((POINT(1,1),0),(0,0));
      		 
      SHOW WARNINGS;


      +---------------------------------+
      		 
      | (1,0) IN ((POINT(1,1),0),(0,0)) |

      +---------+------+-------------------------------------------------------------------------------------------------------------------------------------+

      It's wrong, the expected behavior is to return an error, like a similar scalar query does.

      If I put POINT(1,1) to a deeper level, it also erroneously returns a result with the same warning:

      SELECT (1,(0,0)) IN ((1,(POINT(1,1),0)),(0,(0,0)));


      +---------------------------------------------+
      		 
      | (1,(0,0)) IN ((1,(POINT(1,1),0)),(0,(0,0))) |
      		 
      +---------------------------------------------+
      		 
      |                                           1 |
      		 
      +---------------------------------------------+

      The expected behavior is to return an error.
