[PATCH, ARM] Subregs of VFP registers in big-endian mode

Hi, Quite a few tests fail for big-endian multilibs which use VFP instructions at present. One reason for many of these is glaringly obvious once you notice it: for D registers interpreted as two S registers, the lower-numbered register is always the less-significant part of the value, and the hig
