[Mesa-dev] [PATCH] i965: enable OES_texture_buffer on gen7+

[Ilia Mirkin]

It will only end up getting exposed on gen8+ since it requires GL ES
3.1, but it should be ready to go on gen7 when support for GL ES 3.1 is
completed there.

Tested on SKL on top of Samuel's latest patches to fix up the imageBuffer situation. Passes dEQP-GLES31 *texture_buffer* and *image_load_store*buffer*.
