[Mono-dev] DateTime/DateTimeFormatInfo patch to reduce Clone()

[Atsushi Eno]

Hello,

I noticed that many string[] properties in DateTimeFormatInfo are
used directly in DateTime. They have to return Clone() which are
not neccessary there.

--------
using System;
using System.Globalization;

class Test
{
        public static void Main ()
        {
                for (int i = 0; i < 1000; i++)
                        DateTime.Parse ("2006-11-30T01:01:01.000");
        }
}
--------

After the patch:

If it does not look harmful, I'll commit later.
