When the function test_if_skip_sort_order prefers index backward scan 
to ref access the corresponding access functions must be set accordingly.

 w/ Field_date instead of Field_newdate
  
Field_date was still used in temp table creation.
Fixed by using Field_newdate consistently throughout the server
except when reading tables defined with older MySQL version.
No test suite is possible because both Field_date and Field_newdate
return the same values in all the metadata calls.

The checks in the test for bug #12480 were too wide and
made the test to depend on the procedures and triggers
present in the server.
Corrected the test to check only for the procedure and 
trigger it creates.

In a union without braces, the order by at the end is applied to the 
overall union. It therefore should not interfere with the individual
select parts of the union.

Fixed by changing our parser rules appropriately.
