[M3commit] m3back using Target.Int in place of INTEGER a lot now

[Jay K]

This is fairly large and tedious. If anyone has the patience to look at every single line, please do. Thanks.

I did look through pretty much every single line in search of the one bug I saw working on it.

It turns out the bug was in TWord though. TWord.Multiply(x, 1) = 0.

Which broke INC, it was adding 0 instead 1.

You could see the bug in RTIO.PutString where it just kept outputing the first character.

So I use TInt.Multiply instead.
