[AVX]: Use %vmovd instead of %vmovq

["H.J. Lu" <hjl dot tools at gmail dot com>]

Hi,

I checked in a binutils patch to allow 64bit operands on vmovd:

http://sourceware.org/ml/binutils/2008-05/msg00257.html

I am checking this patch into AVX branch. Joey, Xuepeng, please
make sure that you have the latest binutils.

Thanks.
