i965: Fix shaders that write to gl_PointSize on Sandybridge.

gl_PointSize (VERT_RESULT_PSIZ) doesn't take up a message register,
as it's part of the header.  Without this fix, writing to gl_PointSize
would cause the SF to read and use the wrong attributes, leading to all
kinds of random looking failure.
