Subject: [PATCH] gl_device: Enable compute shaders for Intel proprietary
 drivers

Previously we were disabling compute shaders on Intel's proprietary driver due to broken compute. This has been fixed in the latest Intel drivers. Re-enable compute for Intel proprietary drivers and remove the check for broken compute.
