Timothy Arceri ffa4bbe466 st/nir/radeonsi: move nir_lower_uniforms_to_ubo() to the state tracker
This will only ever be used by gallium drivers so it probably doesn't
belong in the nir toolkit. Also we want to pass it some non NIR
things in the following patch.

To avoid regressions we wrap the lowering calls that have been moved
to st_glsl_to_nir with a quick hack so that they are only called for
radeonsi, we will replace the hack with a check for uniform packing
in a following patch.

Timothy Arceri edded12376 mesa: rework ParameterList to allow packing
Currently everything is padded to 4 components. Making the list
more flexible will allow us to do uniform packing.

V2 (suggestions from Nicolai):
- always pass existing calls to _mesa_add_parameter() true for padd_and_align
- fix bindless param value offsets
- remove left over wip logic from pad and align code
- zero out param value padding
- whitespace fix

Jordan Justen b5baaee0d6 glsl/serialize: Save shader program metadata sha1
When the shader cache is used, this can be generated. In fact, the
shader cache uses this sha1 to lookup the serialized GL shader
program.

If a GL shader program is restored with ProgramBinary, the shaders are
not available, and therefore the correct sha1 cannot be generated. If
this is restored, then we can use the shader cache to restore the
binary programs to the program that was loaded with ProgramBinary.

Alejandro Piñeiro 50767214a7 spirv/radv: add AMD_gcn_shader capability, remove current extensions
So now, during spirv_to_nir, it uses the capability instead of the
extension. Note that we are really doing here is treating
SPV_AMD_gcn_shader as other supported extensions. SPV_AMD_gcn_shader
is not the first SPV extension supported. For example, the capability
draw_parameters infers if the extension SPV_KHR_shader_draw_parameters
is supported or not.

This could be seen as counter-intuitive, and that it would be easier
to define which extensions are supported, and based our checks on
that, but we need to take into account that some capabilities are
optional from core, and others came from new extensions.

Also this commit would make the implementation of ARB_spirv_extensions
easier.

Neil Roberts 25a966a23d spirv: Handle doubles when multiplying a mat by a scalar
The code to handle mat multiplication by a scalar tries to pick either
imul or fmul depending on whether the matrix is float or integer.
However it was doing this by checking whether the base type is float.
This was making it choose the int path for doubles (and presumably
float16s).

A bunch of shaders have sequences like:

Jason Ekstrand 44681e4795 nir: Generalize nir_intrinsic_vote_eq
The SPIR-V extension wants us to be able to do an AllEqual on any vector
or scalar type.  This has two implications:

 1) We need to be able to handle vectors so we switch the vote_eq
    intrinsics to be vectorized intrinsics.

 2) We need to handle floats which have different behavior with respect
    to +-0, NaN, etc. than the integer variant so we need two variants.

Simon Hausmann fb5825e7ce glsl: Fix memory leak with known glsl_type instances
When looking up known glsl_type instances in the various hash tables, we
end up leaking the key instances used for the lookup, as the glsl_type
constructor allocates memory on the global mem_ctx. This patch changes
glsl_type to manage its own memory, which fixes the leak and also allows
getting rid of the global mem_ctx and its mutex.

v2: remove lambda usage (Tapani)
    (+keep ASSERT_BITFIELD_SIZE, modify dummy ctor to initialize mem_ctx)
