gallium/tests/trivial: Import compute unit tests.
Add a test program that tries to exercise some of the language
features commonly used by compute programs at the Gallium API level:
- Correctness of the values returned by the grid parameters.
- Proper functioning of resource LOADs and STOREs.
- Subroutine calls.
- Argument passing to the compute parameter through the INPUT
memory space.
- Mapping of buffer objects to the GLOBAL memory space.
- Proper functioning of the PRIVATE and LOCAL memory spaces.
- Texture sampling and constant buffers.
- Support for multiple kernels in the same program.
- Indirect resource indexing.
- Formatted resource loads and stores (i.e. with channel conversion
and scaling) using several different formats.
- Proper functioning of work-group barriers.
- Atomicity and semantics of the atomic opcodes.
As of now all of them seem to pass on my nvA8.

gallium: Add "pipe-loader" target.
This target generates pipe driver modules intended to be consumed by
auxiliary/pipe-loader. Most of it was taken from the "gbm" target --
the duplicated code will be replaced with references to this target in
a future commit.

gallium: Add pipe loader for device enumeration and driver multiplexing.
The goal is to have a uniform interface to create winsys and
pipe_screen instances for any driver, exposing the device enumeration
capabilities that might be supported by the operating system (for now
there's a "drm" back-end using udev and a "sw" back-end that always
returns the same built-in devices).
The typical use case of this library will be:
>
> struct pipe_loader_device devs[n];
> struct pipe_screen *screen;
>
> pipe_loader_probe(&devs, n);
>[pick some device from the array...]
>
> screen = pipe_loader_create_screen(dev, library_search_path);
>[do something with screen...]
>
> screen->destroy(screen);
> pipe_loader_release(&devs, N);
>
A part of the code was taken from targets/gbm/pipe_loader.c, which
will be removed and replaced with calls into this library by a future
commit.

gallium/compute: Drop TGSI dependency.
Add a shader cap for specifying the preferred shader representation.
Right now the only supported value is TGSI, other enum values will be
added as they are needed.
This is mainly to accommodate AMD's LLVM compiler back-end by letting
it bypass the TGSI representation for compute programs. Other drivers
will keep using the common TGSI instruction set.

gallium/tgsi: Introduce the "LOCAL" register declaration modifier.
This change will be useful to implement function parameter passing on
top of TGSI. As we don't have a proper stack, a register-based
calling convention will be used instead, which isn't necessarily a bad
thing given that GPUs often have plenty of registers to spare.
Using the same register space for local temporaries and
inter-procedural communication caused some inefficiencies, because in
some cases the register allocator would lose the freedom to merge
temporary values together into the same physical register, leading to
suboptimal register (and sometimes, as a side effect, instruction)
usage.
The LOCAL declaration modifier specifies that the value isn't intended
for parameter passing and as a result the compiler doesn't have to
give any guarantees of it being preserved across function boundaries.
Ignoring the LOCAL flag doesn't change the semantics of a valid
program in any way, because local variables are just supposed to get a
more relaxed treatment. IOW, this should be a backwards-compatible
change.

gallium/tgsi: Add support for raw resources.
Normal resource access (e.g. the LOAD TGSI opcode) is supposed to
perform a series of conversions to turn the texture data as it's found
in memory into the target data type.
In compute programs it's often the case that we only want to access
the raw bits as they're stored in some buffer object, and any kind of
channel conversion and scaling is harmful or inefficient, especially
in implementations that lack proper hardware support to take care of
it -- in those cases the conversion has to be implemented in software
and it's likely to result in a performance hit even if the pipe_buffer
and declaration data types are set up in a way that would just pass
the data through.
Add a declaration flag that marks a resource as typeless. No channel
conversion will be performed in that case, and the X coordinate of the
address vector will be interpreted in byte units instead of elements
for obvious reasons.
This is similar to D3D11's ByteAddressBuffer, and will be used to
implement OpenCL's constant arguments. The remaining four compute
memory spaces can also be understood as raw resources.

gallium/tgsi: Split sampler views from shader resources.
This commit splits the current concept of resource into "sampler
views" and "shader resources":
"Sampler views" are textures or buffers that are bound to a given
shader stage and can be read from in conjunction with a sampler
object. They are analogous to OpenGL texture objects or Direct3D
SRVs.
"Shader resources" are textures or buffers that can be read and
written from a shader. There's no support for floating point
coordinates, address wrap modes or filtering, and, unlike sampler
views, shader resources are global for the whole graphics pipeline.
They are analogous to OpenGL image objects (as in
ARB_shader_image_load_store) or Direct3D UAVs.
Most hardware is likely to implement shader resources and sampler
views as separate objects, so, having the distinction at the API level
simplifies things slightly for the driver.
This patch introduces the SVIEW register file with a declaration token
and syntax analogous to the already existing RES register file. After
this change, the SAMPLE_* opcodes no longer accept a resource as
input, but rather a SVIEW object. To preserve the functionality of
reading from a sampler view with integer coordinates, the
SAMPLE_I(_MS) opcodes are introduced which are similar to LOAD(_MS)
but take a SVIEW register instead of a RES register as argument.

gallium: Basic compute interface.
Define an interface that exposes the minimal functionality required to
implement some of the popular compute APIs. This commit adds entry
points to set the grid layout and other state required to keep track
of the usual address spaces employed in compute APIs, to bind a
compute program, and execute it on the device.
