s390x
C1 shared code needs a few platform adaptions for s390. The shared C1 code
is rather close to the target instruction set, therefore some adaptions
for s390 instructions are needed.
In C2 we don't want to idealize ClearArray as s390 has an instructin just doing this, so we add a flag to switch off idealizing this node. Also, in some places, C2 needs mandatory platform adaptions included here.
During output, we have found the need to resize the codebuffer when aligning with nops.
