This allows the software scoreboarding pass, scheduler, and so on
to handle the individual instructions and handle them, rather than
trusting in the generator to do scoreboarding correctly when expanding
the virtual instruction to multiple actual instructions.
By using SHADER_OPCODE_READ_SR_REG, we also correctly handle the
software scoreboarding workaround when reading DMask/VMask.

The hwconfig api may change unexpectedly prior to public release of
new platforms. Also, public documentation of the hwconfig api
sometimes lags the release.
For these reasons, warnings about unhandled hwconfig keys are noisy,
likely to occur, and unhelpful to most users. This commit drops those
warnings, in favor of a separate internal process for tracking
hwconfig api changes.

Currently, res->maybe_busy is false by default. If wait immediately
after the resource is created, virgl_drm_resource_wait() will return
directly without checking the actual state of the kernel, which will
cause synchronization problems, such as:
On Guest:
pipe_buffer_create [mesa]
virgl_drm_winsys_resource_create
virtio_gpu_resource_create_ioctl [kernel]
virtio_gpu_fence_alloc
virtio_gpu_object_create
virtio_gpu_cmd_resource_create_3d
VIRTIO_GPU_CMD_RESOURCE_CREATE_3D
virtio_gpu_object_attach
virtio_gpu_cmd_resource_attach_backing
VIRTIO_GPU_CMD_RESOURCE_ATTACH_BACKING
resource_wait [mesa]
virgl_drm_resource_wait /* return directly without fence waiting */
pipe_buffer_map [mesa]
virgl_drm_resource_map
virtio_gpu_map_ioctl [kernel]
os_mmap
memcpy /* <== here */
On Host (with QEMU):
VIRTIO_GPU_CMD_RESOURCE_CREATE_3D
virgl_cmd_create_resource_3d [qemu]
virgl_renderer_resource_create [virglrenderer]
VIRTIO_GPU_CMD_RESOURCE_ATTACH_BACKING

virgl_resource_attach_iov
vrend_pipe_resource_attach_iov
vrend_write_to_iovec /* <== here */
virtio_gpu_cleanup_mapping_iov [qemu]
In the example above, there is a race condition between memcpy and
vrend_write_to_iovec.

When we don't want to communicate with minio, e.g. running
lava_job_submitter script locally, MINIO_RESULTS_UPLOAD should be unset.
But this variable is already set by generate-env script, so we need to
remove it from the /set-job-env-vars.sh to avoid declaring it in

Is a phi source is an undef, there's no point in copying it or really
caring about it at all. We would just end up inserting a mov from an
undef to a register. Instead, treat phi sources which point to an undef
as if the phi source doesn't exist.
This also prevents them from being included in phi webs which should
reduce the overall interference seen in the shader. Currently, if two
phis share an undef, their phi webs are consdiered to interfere. By
ignoring undefs we can get rid of this false interference and reduce the
size of phi webs. Reducing the number of things being copied by the
parallel copy instructions should also free up the paralle copy
algorithm and reduce the over-all churn of movs.

Undefs can happen even in real GLSL shaders so it's best to handle them.
Lowering to zero is a perfectly valid implementation. Also, run DCE
because some of the undefs may be dead after from_ssa and there's no
point in processing those in the back-end.

This is needed because when we switch between GLES and GL on the host,
we have to lower atomics to ssbo, and with that the shaders can't be
pulled from the cache anymore. Likewise when we move the disk image with
a shader cache to a different host, other features might change that
will need lowering. To avoid using stale shaders in this case, merge the
caps into into the shader cache sha.
