New Mac OS X, old test 新系统，老测试

既然苹果公司在Mac OS X 10.5的矢量库中为Intel的处理器做了大量优化(见加速框架的发布说明)……我来测试下。感谢Lvli007的机器。
Since Apple Inc. is said to make many improves in vecLib of Mac OS X 10.5 to Intel's CPU(SeeAccelerate Release Notes), I'll check it. Thanks to Lvli007 for providing the computer.
Intel Core 2 Duo T7200:

看来确实快了，可以同上次10.4.8下的结果对比。看来经过不懈努力，SSE3还是有可能和Altivec拼一拼的。虽然，那个卷积还是那么寒碜。
但是，我意外地得到了Rosetta下conv的结果：
Ahh… better than previous results under 10.4.8. Seems that after a year's work, SSE3 eventually achieved the same order of Altivec, though the convolution's still poor.
But I got score of conv under Rosetta accidentally:

不仅大大超过了模拟器下其他三项的性能，而且，7倍于Intel原生过程的性能……无语了。补充下，可以生成通用二进制程序的convMP.tar.bz2在此。
Not only speed over the other 3 tests under the emulator, but also 7 times faster than the native routeline for Intel… I have nothing to say about. BTW the convMP.tar.bz2 which can build Universal Binary is here.
