dct64_3dnow.s: Replacement of dct36() with AMD's 3DNow! SIMD operations support

copyright ?-2006 by the mpg123 project - free software under the terms of the LGPL 2.1

initially written by Syuuhei Kashiyama

This code based 'dct36_3dnow.s' by Syuuhei Kashiyama

<squash@mb.kcom.ne.jp>,only two types of changes have been made:

- remove PREFETCH instruction for speedup

- change function name for support 3DNow! automatic detect

You can find Kashiyama's original 3dnow! support patch

(for mpg123-0.59o) at

http://user.ecc.u-tokyo.ac.jp/~g810370/linux-simd/ (Japanese).
