[PATCH] s390: Floating point vector lane handling

Since floating point and vector registers overlap on s390, more efficient code can be generated to extract FPRs from VRs. Additionally, for double vectors, more efficient code can be generated to load specific lanes. gcc/ChangeLog: * config/s390/vector.md (VF): New mode iterator.
