Add VIRGL_BIND_SHADER_BUFFER

See merge request airlied/mesa!1

The guest needs to always mark SSBOs as unclean, since it's possible
the shader can write to them without doing a transfer.

We don't necessarily need to add VIRGL_BIND_SHADER_BUFFER, and we can
do this just with PIPE_BIND_SHADER_BUFFER, but this seemed most
consistent with prior commits.

With some host side changes too, fixes:
    dEQP-GLES31.functional.shaders.builtin_var.compute.num_work_groups

Change-Id: Iafb5ab6bdb4483806709641a5c6f769b0679e636

If we want to upload 16k 32-bit consts we need a bit of overhead
to faciliate that.

Fixes crash in:
KHR-GL44.geometry_shader.limits.max_uniform_components

of tests until we actually support it

The vtest protocol is pretty simple but also pretty dumb, and
the v1 caps query was fixed size, with no nice way to expand it,
however the server also ignores any command it doesn't understand.

So we can query v2 caps by sending a v2 followed by a v1, if the
v2 is ignored we know it's an old vtest server, and the we get
a v2 answer then we can just read the v1 answer and discard it.

As the previous use of shuffle_32bit_load_result_to_64bit_data
had a source/destination overlap for 64-bit. Now a temporary destination
is used for 64-bit cases to use shuffle_from_32bit_read that doesn't
handle src/dst overlaps.

Previously, the shuffle function had a source/destination overlap that
needs to be avoided to use shuffle_from_32bit_read. As we can use for
the shuffle destination the destination of removed MOVs.

This change also avoids the internal MOVs done by the previous shuffle
to deal with possible overlaps.

shuffle_from_32bit_read manages 32-bit reads to 32-bit destination
in the same way that the previous loop so now we just call the new

This implementation avoids two unneeded MOVs for each 64-bit
component. One was done in the old shuffle, to avoid cases of
src/dst overlap but this is not the case. And the removed MOV
was already being being done in the shuffle.

Copy propagation wasn't able to remove them because shuffle
destination values are defined with partial writes because they
have stride == 2.

Using shuffle_from_32bit_read instead of 16-bit shuffle functions

shuffle_from_32bit_read can manage the shuffle/unshuffle needed
for different 8/16/32/64 bit-sizes at VARYING PULL CONSTANT LOAD.
To get the specific component the first_component parameter is used.

In the case of the previous 16-bit shuffle, the shuffle operation was
generating not needed MOVs where its results where never used. This
behaviour passed unnoticed on SIMD16 because dead_code_eliminate
pass removed the generated instructions but for SIMD8 they cound't be
removed because of being partial writes.

These new shuffle functions deal with the shuffle/unshuffle operations
needed for read/write operations using 32-bit components when the
read/written components have a different bit-size (8, 16, 64-bits).
Shuffle from 32-bit to 32-bit becomes a simple MOV.

shuffle_src_to_dst takes care of doing a shuffle when source type is
smaller than destination type and an unshuffle when source type is
bigger than destination. So this new read/write functions just need
to call shuffle_src_to_dst assuming that writes use a 32-bit
destination and reads use a 32-bit source.

As shuffle_for_32bit_write/from_32bit_read components take components
in unit of source/destination types and shuffle_src_to_dst takes units
of the smallest type component, we adjust components and first_component
parameters.

To enable this new functions it is needed than there is no
source/destination overlap in the case of shuffle_from_32bit_read.
That never happens on shuffle_for_32bit_write as it allocates a new
destination register as it was at shuffle_64bit_data_for_32bit_write.

This new function takes care of shuffle/unshuffle components of a
particular bit-size in components with a different bit-size.

If source type size is smaller than destination type size the operation
needed is a component shuffle. The opposite case would be an unshuffle.

Component units are measured in terms of the smaller type between
source and destination. As we are un/shuffling the smaller components
from/into a bigger one.

The operation allows to skip first_component number of components from
the source.

Shuffle MOVs are retyped using integer types avoiding problems with
denorms and float types if source and destination bitsize is different.
This allows to simplify uses of shuffle functions that are dealing with
these retypes individually.

Now there is a new restriction so source and destination can not overlap
anymore when calling this shuffle function. Following patches that migrate
to use this new function will take care individually of avoiding source
and destination overlaps.

v2: (Jason Ekstrand)
    - Rewrite overlap asserts.
    - Manage type_sz(src.type) == type_sz(dst.type) case using MOVs
      from source to dest. This works for 64-bit to 64-bits
      operation that on Gen7 as it doesn't support Q registers.
    - Explain that components units are based in the smallest type.
v3: - Fix unshuffle overlap assert (Jason Ekstrand)
