freedreno/ir3: start dealing with half-precision

Some instructions, assume src and/or dst is half-precision based on a
type field (ie. f32/s32/u32 are full precision but others are half
precision).  So add some code to sanity check the src/dst registers to

Also propagate half-precision flag for SSA sources.  The instruction
consuming a SSA value needs to be of the same type as the one producing
it.

This is probably not complete half-precision support, but a useful first

loader: Add support for platform and host1x busses

ARM SoCs usually have their DRM/KMS devices on the platform bus, so add
support for this bus in order to allow use of the DRI_PRIME environment
variable with those devices.

While at it, also support the host1x bus, which is effectively the same
but uses an additional layer in the bus hierarchy.

Note that it isn't enough to support the bus that has the rendering GPU
because the loader code will also try to construct an ID path tag for a
scanout-only device if it is the default that is being opened.

The ID path tag for a device can be obtained by running udevadm info on
the device node, as shown in this example on NVIDIA Tegra:

$ udevadm info /dev/dri/card0 | grep ID_PATH_TAG
E: ID_PATH_TAG=platform-50000000_host1x

The corresponding OF_FULLNAME property, from which the ID_PATH_TAG is
constructed, can be found in the sysfs "uevent" attribute for the card0
device's parent:

$ grep OF_FULLNAME /sys/devices/platform/50000000.host1x/drm/uevent
OF_FULLNAME=/host1x@50000000

Similarily, /dev/dri/card1 corresponds to the GPU:

$ udevadm info /dev/dri/card1 | grep ID_PATH_TAG
E: ID_PATH_TAG=platform-57000000_gpu

and:

$ grep OF_FULLNAME /sys/devices/platform/57000000.gpu/uevent
OF_FULLNAME=/gpu@57000000

- avoid confusing pre-increment in strdup()

disk cache: Link with -latomic if necessary

The disk cache implementation uses 64-bit atomic operations. For some
architectures, such as 32-bit ARM, GCC will not be able to translate
these operations into atomic, lock-free instructions and will instead
rely on the external atomics library to provide these operations.

Check at configuration time whether or not linking against libatomic
is necessary and if so, create a dependency that can be used while
linking the mesautil library.

This is the meson equivalent of 2ef7f23820a6 ("configure: check if
-latomic is needed for __atomic_*").

For some background information on this, see:

https://gcc.gnu.org/wiki/Atomic/GCCMM

Changes in v2:
- clarify meaning of lock-free in commit message
- fix build if -latomic is not necessary

radv: do not set pending_reset_query in BeginCommandBuffer()

This is just useless for two reasons:
1) flush_bits is not set accordingly, so nothing will be flushed
   in BeginQuery().
2) we always flush caches in EndCommandBuffer(), so if a reset
   is done in a previous command buffer we are safe.

i965: Allow 48-bit addressing on Gen8+.

This allows most GPU objects to use the full 48-bit address space
offered by Gen8+ platforms, rather than being stuck with 32-bit.
This expands the available GPU memory from 4G to 256TB or so.

A few objects - instruction, scratch, and vertex buffers - need to
remain pinned in the low 4GB of the address space for various reasons.
We default everything to 48-bit but disable it in those cases.

Thanks to Jason Ekstrand for blazing this trail in anv first and
finding the nasty undocumented hardware issues.  This patch simply
rips off all of his findings.

This makes the name shorter in debug printouts.  If "workaround_bo"

intel/fs: Set up sampler message headers in the visitor on gen7+

This gives the scheduler visibility into the headers which should
improve scheduling.  More importantly, however, it lets the scheduler
know that the header gets written.  As-is, the scheduler thinks that a
texture instruction only reads it's payload and is unaware that it may
write to the first register so it may reorder it with respect to a read
from that register.  This is causing issues in a couple of Dota 2 vertex
shaders.
