2ea15cd661 d3d12: introduce d3d12 gallium driver
This driver will allow running OpenGL and OpenCL on top of Gallium
for any hardware supporting Microsoft's Direct3D 12 on Windows 10.

This is the combination of a lot of commits from our development branch,
containing code from several authors.

b9c61379ab microsoft/compiler: translate nir to dxil
Here's the code to emit DXIL code from NIR. It's big and bulky as-is,
and it needs to be split up a bit.

This is the combination of a lot of commits from our development branch,
containing code by several authors.

dd5fe2f3de microsoft/compiler: add dxil-util code
This is support-code to emit the DirectX Intermediate Language, which is
a dialect of LLVM 3.7 bitcode. Because modern versions of LLVM doesn't
support emitting bitcode for older versions, and we can't rely on an old
LLVM version because we need the OpenCL support from Clang later on, we
instead implement our own LLVM bitcode encoder as part of this work.

See the official DXIL documentation for more details on DXIL:
https://github.com/Microsoft/DirectXShaderCompiler/blob/master/docs/DXIL.rst

The reason this comes as a separate library, is because we're also using
this code as the basis for an OpenCL C compiler, which will follow as a
separate merge-request later.

This is the combination of more than 230 commits from our development
branch, including the work from several authors.

Adds template support to zink_device_info.py for setting up the VkPhysicalDeviceVulkan* version Features and Properties structures.
When the next Vulkan version with newer structure is released a single like should only need to be added.
Note, the 11 structures where not added until Vk 1.2, so that is not a typo.
This code does not stop the use of clonflicting extensions or other VkPhysicalDevice*Features structures with VkPhysicalDeviceVulkan*Features structures when calling vkCreateDevice()

a1a365e818 broadcom/compiler: Allow spills of temporaries from TMU reads
Since spills and fills use the TMU, special care has to be taken to
avoid putting one between a TMU setup instruction and the corresponding
reads or writes. This change adds logic to move fills up and move spills
down to avoid interrupting such sequences.

This allows compiling 6 more programs from shader-db. Other stats:

spills in affected programs: 0 -> 0

23dbf7964b panfrost: Force late pixel kill when depth/stencil is written from the FS
If we don't do that, pixels might be killed early thus preventing the
fragment shader from being called and updating the depth/stencil value.

956228da3a radeon/vcn : Corrected dpb_size calculation for VP9_2
Currently dpb_size for VP9 profile0 and profile2 is same eventhough
for profile2 dpb_size is  multiplied by extra 3/2 and we are
seeing VM_L2_PROTECTION_FAULT error and ring vcn_dec timeout because
of less dpb_size for VP9_2.

This patch will correct dpb_size for VP9_2 and fixes the issue.

68092df8d8 intel/nir: Lower 8-bit ops to 16-bit in NIR on Gen11+
Intel hardware supports 8-bit arithmetic but it's tricky and annoying:

  - Byte operations don't actually execute with a byte type.  The
    execution type for byte operations is actually word.  (I don't know
    if this has implications for the HW implementation.  Probably?)

  - Destinations are required to be strided out to at least the
    execution type size.  This means that B-type operations always have
    a stride of at least 2.  This means wreaks havoc on the back-end in
    multiple ways.

  - Thanks to the strided destination, we don't actually save register
    space by storing things in bytes.  We could, in theory, interleave
    two byte values into a single 2B-strided register but that's both a
    pain for RA and would lead to piles of false dependencies pre-Gen12
    and on Gen12+, we'd need some significant improvements to the SWSB
    pass.

  - Also thanks to the strided destination, all byte writes are treated
    as partial writes by the back-end and we don't know how to copy-prop
    them.

  - On Gen11, they added a new hardware restriction that byte types
    aren't allowed in the 2nd and 3rd sources of instructions.  This
    means that we have to emit B->W conversions all over to resolve
    things.  If we emit said conversions in NIR, instead, there's a
    chance NIR can get rid of some of them for us.

We can get rid of a lot of this pain by just asking NIR to get rid of
8-bit arithmetic for us.  It may lead to a few more conversions in some
cases but having back-end copy-prop actually work is probably a bigger
bonus.  There is still a bit we have to handle in the back-end.  In
particular, basic MOVs and conversions because 8-bit load/store ops
still require 8-bit types.

b98f0d3d7c intel/nir: Lower 8-bit scan/reduce ops to 16-bit
We can't really support these directly on any platform.  May as well let
NIR lower them.  The NIR lowering is potentially one more instruction
for scan/reduce ops thanks to not being able to do the B->W conversion
as part of SEL_EXEC.  For imax/imin exclusive scan, it's yet another
instruction thanks to the extra imax/imin NIR has to insert to deal with
the fact that the first live channel will contain the identity value
which, when signed, will cast wrong.  However, it does let us drop some
complexity from our back-end so it's probably worth it.

15c6e05a72 nir/lower_bit_size: Don't cast comparison results
Some ALU ops (comparisons being the primary example) have a fixed
bit-size destination and, in that case, we don't want to insert a
conversion on the destination.
