target-ppc: Correct VSX FP to FP Conversions
This change corrects the VSX double precision to single precision and single precision to double precisions conversion routines. The endian correct accessors are now used. The auxiliary "j" index is no longer necessary and is eliminated. Signed-off-by: Tom Musta <tommusta@gmail.com> Tested-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>
