ee38cce1bf Fix toUnixTimestamp(Date()) error (use type name not column type name) 
Was:
    Code: 44. DB::Exception: Received from localhost:9000. DB::Exception: Illegal column UInt16 of first argument of function toUnixTimestamp: While processing toUnixTimestamp(today()).

Now:
    Code: 44. DB::Exception: Received from localhost:9000. DB::Exception: Illegal type Date of first argument of function toUnixTimestamp: While processing toUnixTimestamp(today()).

17f6c82ffa Prohibit toUnixTimestamp(Date()) 
Making it implicitly cast to Date() does not looks correct, since before
it returns somewhat unexpected result:

    SELECT toUnixTimestamp(today())

    ┌─toUnixTimestamp(today())─┐
    │                    18591 │
    └──────────────────────────┘

4713b59159 Fix CAST(Nullable(String), Enum()) 
The wrapper that is returned from createStringToEnumWrapper() does not
have access to the ColumnNullable (i.e. original column), because it is
converted to nested type in the prepareRemoveNullable().

So add original ColumnNullable into the block in prepareRemoveNullable()
if source type is Nullable and pass this flag to the
createStringToEnumWrapper() to make it know about that fact that last
column in the block is the original ColumnNullable in this case.

And this one looks most sane.
