Fixed bug #19714. 

DESCRIBE returned the type BIGINT for a column of a view if the column
was specified by an expression over values of the type INT.
    
E.g. for the view defined as follows:
  CREATE VIEW v1 SELECT COALESCE(f1,f2) FROM t1
DESCRIBE returned type BIGINT for the only column of the view if f1,f2 are
columns of the INT type.
At the same time DESCRIBE returned type INT for the only column of the table
defined by the statement:
  CREATE TABLE t2 SELECT COALESCE(f1,f2) FROM t1.
    
This inconsistency was removed by the patch.

Now the code chooses between INT/BIGINT depending on the
precision of the aggregated column type.
 
Thus both DESCRIBE commands above returns type INT for v1 and t2.
