For newer hardware we disable the VBO module's software handling
of primitive restart. We now handle primitive restarts in
brw_handle_primitive_restart.
The initial version of brw_handle_primitive_restart simply calls
vbo_sw_primitive_restart, and therefore still uses the VBO
module software primitive restart support.

v2: Add support for gen6, and don't turn it on if blending is
disabled. (fixes GPU hang), and note it in docs/GL3.txt

All I know of that needs finishing in Mesa is to enable the extension
in a GL3.1 core context on i965 -- we're not going to expose it in
non-3.1 core contexts.

It's the same as GL_AMD_conservative_depth. The specs have slight
differences in wording, but don't differ in content or behavior.

Since we lack hardware support for it, this is a simple matter of
checking _mesa_check_conditional_render at the entrypoints, and
suppressing it for the metaops where it doesn't apply.

Things definitely remaining todo: switch statements, clip distances.
On 965, we also need real integers in the VS, and implementations of
some things like isinf/isnan.

This gets my vote for most pointless extension of all time, I'm guessing
some driver could possibly optimise for this instead of counting it might
just get a true/false, but I'm not really sure.
need this to eventually advertise 3.3 despite its total uselessness.
