S/390: idte/ipte fixes
Later CPU generations added optional operands to the ipte/idte
instructions. I've added these with:
https://sourceware.org/ml/binutils/2017-05/msg00316.html ... but
supported the optional operands only with the specific hardware
levels. However, it is more useful to have the optional operands
already in the first versions. Of course they need to be zero there.
Regression-tested with on s390 and s390x. Committed to mainline.
Bye,
