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 5a79859ae0f3 ("s390: remove 31 bit support").
