The only reason for the separate opcode was because of the overlapping
BRW_AOP_* enums, making it impossible to tell whether a particular AOP
was the integer or float operation. Now that we use the lsc_opcode
enums, we can just have the legacy lowering inspect the opcode and
select the right descriptor. No need for a separate opcode.

This gets our logical atomic messages using the lsc_opcode enum rather
than the legacy BRW_AOP_* defines. We have to translate one way or
another, and using the modern set makes sense going forward.
One advantage is that the lsc_opcode encoding has opcodes for both
integer and floating point atomics in the same enum, whereas the legacy
encoding used overlapping values (BRW_AOP_AND == 1 == BRW_AOP_FMAX),
which made it impossible to handle both sensibly in common code.

This avoids a violation of the Vulkan memory model that was leading to
intermittent failures of at least 8k test-cases of the Vulkan CTS
(within the group dEQP-VK.memory_model.*) on TGL and DG2 platforms.
In theory the issue may be reproducible on earlier platforms like IVB
and ICL, but the SYNC.ALLWR instruction is not available on those
platforms so a different (likely costlier) fix will be needed.
The issue occurs within the sequence we emit for a NIR memory barrier
with acquire semantics requiring the synchronization of multiple
caches, e.g. in pseudocode for a barrier involving the TGM and UGM
caches on DG2:
x <- load.ugm // Atomic read sequenced-before the barrier
y <- fence.ugm
z <- fence.tgm
wait(y, z)
w <- load.tgm // Read sequenced-after the barrier
In the example we must provide the guarantee that the memory load for
x is completed before the one for w, however this ordering can be
reversed with the intervention of a concurrent thread, since the UGM
fence will block on the prior UGM load and potentially take a long
time, while the TGM fence may complete and invalidate the TGM cache
immediately, so a concurrent thread could pollute the TGM cache with
stale contents for the w location *before* the UGM load has completed,
leading to an inversion of the expected memory ordering.
v2: Apply the workaround regardless of whether the NIR barrier
intrinsic specifies multiple storage classes or a single one,
since an acquire barrier is required to order subsequent requests
relative to previous atomic requests of unknown storage class not
necessarily specified by the memory scope information of the
intrinsic.

nir/lower_blend asserts:
assert(nir_intrinsic_write_mask(store) ==
nir_component_mask(store->num_components));
For the special blend shaders used in Panfrost, this holds. But for arbitrary
shaders coming out of GLSL-to-NIR (as used with Asahi), this does not hold. In
particular, after nir_opt_undef runs, undefined components can be trimmed.
Concretely, if we have the shader:
gl_FragColor.xyz = foo;
Then this becomes in NIR
gl_FragColor = vec4(foo.xyz, undef);
and then opt_undef will give the store_deref a wrmask of xyz but 4 components.
Then lower_blend asserts out.
Found in a gfxbench shader on asahi.

This patch is comprised of three main changes:
- Add a "shim" for GDI, since Xbox doesn't expose this library
- New framebuffer file, to support the Xbox "windowing" system
- Implement a custom WndProc hook for Xbox, since SetWindowsHookEx isn't supported either
Other than that, it's similar to the previous Xbox commits which mostly disable Win32-specific logic.

Three reasons for that:
0. The operation we're doing here is actually a reallocation.
1. The newer code is, IMHO, easier to read.
2. Realloc has this property where sometimes, when possible, it will
expand your array without moving it somewhere else, so it doesn't
need to copy the memory contents, returning the original pointer
back to you. I did some analysis and while that case is not common,
it does happen sometimes in real world applications (I could see it
happening in Shootergame and Aztec Ruins, but not Dota 2), so we're
able to save a few CPU cycles.

This is the only code path where we don't run anv_execbuf_finish() in
case anv_execbuf_add_bo() fails. While there is not a bug in the
current tree, I recently made an (uncommitted) modification that
started leaking memory and made me realize the lack of cleanup here.
If we had anv_execbuf_finish() being called upon error like we're
going to have after this patch my modification wouldn't have caused
the memory leak.
I think it's much safer and future-proof if we're able to operate
under the assumption that whatever is allocated and set to anv_execbuf
will be dealt with upon failure of anything else related to it, so
functions that fail should only be required to free pointers not yet
assigned to anv_execbuf.
The dEQP-VK 'alloc_callback_fail' tests should exercise this code
path. The one I was specifically using here is:

add_bo_biset() was specifically exercised. Anyway, add the error check

In anv_execbuf_add_syncobj(), we try to not create or use
exec->syncobj_values if we don't need to. But when we figure we're
going to need it (i.e., when timeline_value is not zero), then we
create exec->syncobj_values with vk_zalloc, which means every previous
value is set to zero, as it should be. This is all correct.
The problem starts when we add a 16th element. In this case we double
exec->syncobj_array_length and realloc the buffer by using vk_alloc
and copying the old array to the new one. After that, we write the
timeline_value to the array only if it's not zero, and that's the
problem: since we just used vkalloc and memcpy, we don't have any
guarantees that the new array will be zero after the 16th element, and
if timeline_value is zero we write nothing to that position.
Once we start using exec->syncobj_values we have to commit to using
it, so the "if (timeline_value)" check near the end of the function
has to be changed to "if (exec->syncobj_values)", so we actually set
elements after the 16th to zero when they need to be zero. Another
approach to fix this would be to memset the new elements once we
double syncobj_array_length.
In practice, I couldn't find any application or deqp test that used
more than 3 elements in exec->syncobj_array_length, and we need more
than 16 elements in order to be able to reproduce the bug, so I'm not
aware of any real-world bug that goes away with this patch. This issue
was found while reading code.
If we craft a little Vulkan program that submits a ton of timeline and
binary semaphores on vkQueueSubmit, then waits for them, we get the
following error without this patch:
MESA: error: ../../src/intel/vulkan/anv_batch_chain.c:1910: execbuf2 failed: Invalid argument (VK_ERROR_DEVICE_LOST)
