Pixman Loongson SIMD optimization

contact project's owner by wgge7270@gmail.com
Pixman is a low level compositing library for X and Cairo. The first release enabled most of the composite functions. The performance gain is not as big as I have expected. Most of the composite sees 20-30% in lowlevel-benchmark, some sees 100% boost or more. Overall performance depends on user scenario.

只在2F平台测试过，2E平台慎用。

Installation:
git clone ​git://dev.lemote.com/Pixman.Loongson.git --branch loongson
cd Pixman.Loongson
./autogen.sh --prefix=/usr
make

用下面的命令测试是否通过，不通过不要安装：
test/blitters-test

通过再安装：
sudo make install
