Yeah... I started writing the extension when Chris Forbes was working on
adding GLSL 1.30 for Ironlake.  I seem to recall that gl_ClipDistance
still does not work for ILK, and difficulties with that caused Chris to
abandon the project.  This was over a year ago, so the details are a bit
fuzzy.

The common Mesa parts look good, though.  If we want to pursue this, I
can finish up the extension spec and get it published.

One other minor nit below...

This should go with the existing (brw->gen >= 5) block elsewhere in this
function.  I should also look like the EXT_shader_integer_mix initializer:

      ctx->Extensions.EXT_shader_integer_mix = ctx->Const.GLSLVersion >=
130;

Then this part could land independently of the hunk below.
