i965: Bump GL_MAX_CUBE_MAP_TEXTURE_SIZE to 8192.
Gen4+ supports 8192x8192 cube maps. Ivybridge and later can actually
support 16384, but that would place GL_MAX_CUBE_MAP_TEXTURE_SIZE above
GL_MAX_TEXTURE_SIZE, which seems like a bad idea.
(Unfortunately, we can't bump GL_MAX_TEXTURE_SIZE to 16384 without
causing regressions due to awful W-tiled stencil buffer interactions.)
