Bug #21103: DATE column not compared as DATE 

If we compare two items A and B, with B being (a constant) of a
larger type, then A gets promoted to B's type for comparison if
it's a constant, function, or CAST() column, but B gets demoted
to A's type if A is a (not explicitly CAST()) column. This is
counter-intuitive and not mandated by the standard.
 
Disabling optimisation where it would be lossy so field value
will properly get promoted and compared as binary string (rather
than as integers).

  When comparing a DATE field with a DATETIME constant, we now compare
  as DATETIMEs, not as DATEs.  Fix certain queries to still work.
