target-ppc: Correct LE Host Inversion of Lower VSRs
This change properly orders the doublewords of the VSRs 0-31.  Because these
registers are constructed from separate doublewords, they must be inverted
on Little Endian hosts.  The inversion is performed both when the VSR is read
and when it is written.
