Re: Mesa (master): i965: Don't write mrf assignment for pointsize output

[Shuang He]

For you information:
This commit fixes 17 OpenGL ES 2.0 conformance cases on i965
And also another 1 commit from Ken also fixes 1 case
So We have 18 more passes on OpenGL ES 2.0 conformance on i965 these two 
days

Thanks
