glsl: reuse main extension table to appropriately restrict extensions
Previously we were only restricting based on ES/non-ES-ness and whether
the overall enable bit had been flipped on. However we have been adding
more fine-grained restrictions, such as based on compat profiles, as
well as specific ES versions. Most of the time this doesn't matter, but
it can create awkward situations and duplication of logic.
Here we separate the main extension table into a separate object file,
linked to the glsl compiler, which makes use of it with a custom
function which takes the ES-ness of the shader into account (thus
allowing desktop shaders to properly use ES extensions that would
otherwise have been disallowed.) We can also now use this logic to
generate #define's for all supported extensions automatically, removing
the duplicate (and often inaccurate) list in glcpp.
The effect of this change should be nil in most cases. However in some
situations, extensions like GL_ARB_gpu_shader5 which were formerly
available in compat contexts on the GLSL side of things will now become
inaccessible.
This regresses two ES CTS tests:
ES3-CTS.shaders.shader_integer_mix.define
ES31-CTS.shader_integer_mix.define
however that is due to them using #version 100 instead of 300 es. As the
extension is only defined for ES3, I believe this is the correct
behavior.

mesa: Add GL_BGRA_EXT to the list of GenerateMipmap internal formats.
The GL_EXT_texture_format_BGRA8888 extension specification defines a
GL_BGRA_EXT unsized internal format (which is a little odd - usually
BGRA is a pixel transfer format). The extension is written against
the ES 1.0 specification, so it's a little hard to map, but I believe
it's effectively adding it to the table used here, so we should allow
it here as well.

This eliminates the need to walk the list of input variables, recurse

trying to pack multiple variables into the same location. Instead,

This should unblock Timothy's work on GL_ARB_enhanced_layouts.
Each load_interpolated_input intrinsic corresponds to PLN instructions,
while load_barycentric_at_* intrinsics correspond to pixel interpolator
messages. The pixel/centroid/sample barycentric intrinsics simply refer
to payload fields (delta_xy[]), and don't actually generate any code.
Because we use a single intrinsic for both centroid-qualified variables

sending pixel interpolator messages for those, and instead use the
payload provided data, which should be considerably faster.

i965: Move load_interpolated_input/barycentric_* intrinsics to the top.
Currently, i965 interpolates all FS inputs at the top of the program.
This has advantages and disadvantages, but I'd like to keep that policy
while reworking this code. We can consider changing it independently.
The next patch will make the compiler generate PLN instructions "on the
fly", when it encounters an input load intrinsic, rather than doing it
for all inputs at the start of the program.
To emulate this behavior, we introduce an ugly pass to move all NIR
load_interpolated_input and payload-based (not interpolator message)
load_barycentric_* intrinsics to the shader's start block.
This helps avoid regressions in shader-db for cases such as:
if (...) {
...load some input...
} else {
...load that same input...
}
which CSE can't handle, because there's no dominance relationship
between the two loads. Because the start block dominates all others,
we can CSE all inputs and emit PLNs exactly once, as we did before.
Ideally, global value numbering would eliminate these redundant loads,
while not forcing them all the way to the start block. When that lands,
we should consider dropping this hacky pass.
Again, this pass currently does nothing, as i965 doesn't generate these
intrinsics yet. But it will shortly, and I figured I'd separate this
code as it's relatively self-contained.

nir: Add new intrinsics for fragment shader input interpolation.
Backends can normally handle shader inputs solely by looking at
load_input intrinsics, and ignore the nir_variables in nir->inputs.
One exception is fragment shader inputs. load_input doesn't capture
the necessary interpolation information - flat, smooth, noperspective
mode, and centroid, sample, or pixel for the location. This means
that backends have to interpolate based on the nir_variables, then
associate those with the load_input intrinsics (say, by storing a
map of which variables are at which locations).
With GL_ARB_enhanced_layouts, we're going to have multiple varyings
packed into a single vec4 location. The intrinsics make this easy:
simply load N components from location <loc, component>. However,
working with variables and correlating the two is very awkward; we'd
much rather have intrinsics capture all the necessary information.
Fragment shader input interpolation typically works by producing a
set of barycentric coordinates, then using those to do a linear
interpolation between the values at the triangle's corners.
We represent this by introducing five new load_barycentric_* intrinsics:
- load_barycentric_pixel (ordinary variable)
- load_barycentric_centroid (centroid qualified variable)
- load_barycentric_sample (sample qualified variable)
- load_barycentric_at_sample (ARB_gpu_shader5's interpolateAtSample())
- load_barycentric_at_offset (ARB_gpu_shader5's interpolateAtOffset())
Each of these take the interpolation mode (smooth or noperspective only)
as a const_index, and produce a vec2. The last two also take a sample
or offset source.
We then introduce a new load_interpolated_input intrinsic, which
is like a normal load_input intrinsic, but with an additional
barycentric coordinate source.
The intention is that flat inputs will still use regular load_input
intrinsics. This makes them distinguishable from normal inputs that
need fancy interpolation, while also providing all the necessary data.
This nicely unifies regular inputs and interpolateAt functions.
Qualifiers and variables become irrelevant; there are just
load_barycentric intrinsics that determine the interpolation.
v2: Document the interp_mode const_index value, define a new
BARYCENTRIC() helper rather than using SYSTEM_VALUE() for
some of them (requested by Jason Ekstrand).

genxml: Rename "API Rendering Disable" to "Rendering Disable".
Gen7/7.5 call it "Rendering Disable" while Gen8/9 prefix it with "API".
Pick one for consistency, and so we can share code between generations.

anv: Unify 3DSTATE_CLIP code across generations.
The bulk of this is the same. There are just a couple fields that only
exist on one generation or another, and we can easily handle those with
an #ifdef.

We set the cull mode, but forgot the enable bit. Gen8 uses this.
