	* IntegerFormatter.cs: Avoid .ToCharArray, it was being used in
	places where there was no reason for it. Also, allocate buffers
	using stackalloc. This avoids the cost of allocating a char []
	buffer in the gc. Also did some minor style changes.

	This gives a huge reduction in memory allocation for integer formatting.
	often you see something like:

	665 KB System.IntegerFormatter::FormatGeneral(long,int,NumberFormatInfo,bool,int)
	    463 KB    11710 System.Char[]
	    201 KB    11710 System.String

	This patch removes the char [] part. (it also removes the
	tochararray, which accounts for even more.
