s390x: Add support for emitting "vector or with complement"

In the instruction selector, look out for IR expressions that fit "vector
or with complement (VOC)".  Emit when applicable.

This slighly reduces the generated code sometimes, such as for certain
vector string instructions, where such expressions occur quite frequently.
