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 5a79859a
("s390: remove 31 bit support").
