Unclear example for sign extension

[333fred]

The code example we have for CS0675 is not particularly clear, as it doesn't really show the problem: it just becomes 0x100000001, which is exactly what was asked for. Instead, we should probably show (long)1 | -1, as that will give 0xFFFFFFFF_FFFFFFFF rather than 0x00000001_FFFFFFFF, which is what one might expect to get when |ing an int and a long here. It would also be good to show the results of | operations, rather than just saying one is correct and one is not.

Thanks @333fred
