G80架构信息更新

Edison

Rather than wonder about a discrete CB cache, I changed it to read that there definitely is one since we've since confirmed that's the case.
Confirmation that scheduler clock runs at half the shader clock (675MHz for 8800 GTX f.e.).
Confirmation that the missing MUL is serial to interp/SF and not available for general shading just now.
Confirmation that SPs are arranged '8x2' in a G80 shader cluster.
Confirmation that each cluster has its own dedicated register space rather than wondering.

其实也没有什么特别。
