s390: introduce register pair union

Introduce a register pair union, which is supposed to be used for
inline assemblies where instructions require parameters in even/odd
numbered register pairs.

This is more or less the same register pair construct which was
available for 31 bit builds which was removed with commit 1796ea228d5f
("s390: remove 31 bit support").
