The quadop-based method we currently use on all chipsets already
provides the fine version of the derivatives.

This extension is identical to NV_texture_barrier. Alias
glTextureBarrier to the existing glTextureBarrierNV and use the existing
NV_texture_barrier extension bit.

This just cherry-pick the extensions into a list for GLES 3.1
I'm not actually sure if this list if complete or correct, maybe someone
else can tell me what I missed, and I'm not 100% sure on multi_draw_indirect.

Listing the GLSL version as an individual component of a GL version,
separate from the extensions isn't really right. The GLSL changes are
(almost?) entirely comprised of changes listed in the extensions.

Adds 0-3 textureGather component selection and non-constant offsets
Caveat: 0 and 1 texture swizzles only work if textureGather component
select is 3 or a component that does not exist in the sampler texture
format. This is a hardware limitation, any other value returns
128/255=0.501961 for both 0 and 1.
Passes all textureGather piglit tests on radeon 6670, except for those
using 0/1 texture swizzles due to aforementioned reason.

Only supported on evergreen and later. Currently limited
to single component textures as the hardware GATHER4
instruction ignores texture swizzles.
Piglit quick run passes on radeon 6670 with all
applicable textureGather tests, no regressions.

If multiple viewports are supported, that implies the presence of a GS
and layered rendering, so we can enable ARB_fragment_layer_viewport as
well.

The extension is always supported if GLSL 1.30 is supported.
Softpipe and llvmpipe support is also added (trivial).
Radeon and nouveau support is already done.
