Please add foreach like in D69010. Here and below.

1014

Also needs foreach,

[dp]

Updated by integrating changes from D69010.

[rampitec]

Still missing foreach around dpp.

I added them but found no differences in *.inc files.
Are they necessary as a reserve for the future?

Yes, it is better to have them so we do not have to check every time we are not producing garbage.

[dp]

Added more guards to avoid generating unused instructions.
