43abaf2ad0 mesa: remove unused vertex attrib WEIGHT
We don't support ARB_vertex_blend.

Note that the attribute aliasing check for ARB_vertex_program had to be
rewritten.

vbo_context: 20344 -> 20008 bytes
gl_context: 74672 -> 74616 bytes

c34295b1a3 nir: Move vc4's alpha test lowering to core NIR.
I've been doing this inside of vc4, but vc5 wants it as well and it may be
useful for other drivers (Intel has a related path for pre-gen6 with MRT,
and freedreno had a TGSI path for it at one point).

This required defining a common enum for the standard comparison
functions, but other lowering passes are likely to also want that enum.

v2: Add to meson.build as well.

ac1181ffbe compiler: Rename INTERP_QUALIFIER_* to INTERP_MODE_*.
Likewise, rename the enum type to glsl_interp_mode.

Beyond the GLSL front-end, talking about "interpolation modes" seems
more natural than "interpolation qualifiers" - in the IR, we're removed
from how exactly the source language specifies how to interpolate an
input.  Also, SPIR-V calls these "decorations" rather than "qualifiers".

39103145ff glsl/shader_enums: Add the other two compute builtins
These weren't added before because they are actually calculated values that
are computed from other inputs.  However, in order to handle them in
nir_lower_system_values, it's nice for them to have a cannonical locaiton.

35f8488668 glsl: keep track of ssbo variable being accessed, add access params
Currently any access params (coherent/volatile/restrict) are being lost
when lowering to the ssbo load/store intrinsics. Keep track of the
variable being used, and bake its access params in as the last arg of
the load/store intrinsics.

If the variable is accessed via an instance block, then 'variable'
points to the instance block variable and not the field inside the
instance block that we are accessing. In order to check access
parameters for the field itself we need to detect this case and keep
track of the corresponding field struct so we can extract the specific
field access information from there instead.
