IBM Z: Fix long double <-> DFP conversions
When switching the s390 backend to store long doubles in vector
registers, the patterns for long double <-> DFP conversions were
forgotten. This did not cause observable problems so far, because
libdfp calls are emitted instead of pfpo. However, when building
libdfp itself, this leads to infinite recursion.
