In cases where the to-be-allocated node size with padding exceeds BLOCK_SIZE
but without padding doesn't, a new block is not created and no padding is done
to the previous instruction, causing a misaligned pointer to be returned.
v2: Per Ilia Mirkin's suggestion, remove the extra condition in the first
if statement, let it unconditionally pad the last instruction if needed.
The updated currentPos will then be taken into account in the
block size checking.

The limit here is from the RENDER_SURFACE_STATE height/width/depth
fields - it's 2^30 for ISL_FORMAT_RAW buffers, and 2^27 otherwise.
anv_isl_format_for_descriptor_type() uses ISL_FORMAT_R32G32B32A32_FLOAT
for uniform buffers when compiler->indirect_ubos_use_sampler is set
(Icelake and earlier), but ISL_FORMAT_RAW when it isn't (Tigerlake+).
So we can increase the limit on Tigerlake and later.

We are updating the deadcode state while walking the program backwards.
When encountering ENDLOOP, we scan the loop, mark everything in the loop
as used and than continue as usuall. We were previously trying to be
smart with the breaks. This was however not working as expected.
Instead, save the most pesimistic deadcode state from the ENDLOOP and
just restore it anytime we see a break.
This keeps the code simple and more importantly does not touch the flat
and IF(-ELSE)-ENDIF paths at all so reduces the chances of regression.
No changes with my shader-db.

Compute shaders might do vec3(Xbits) loads which are translated
to LD.<next_pow2(3 * X)> by the midgard compiler. This might cause
out-of-bound accesses potentially leading to pagefaults if the
access is at the end of a BO. One solution to avoid that (maybe not
the best) is to split non-log2 loads to make sure we only read what's
requested.

Swizzling happens in 2 steps on Midgard:
1. Vector expansion/shuffling
2. Swizzling at the instruction-size granularity, but defined using
the source size. Those size are different if the source is expanded.
So, when we print 64 bit swizzles on an expanded source, we first need
to apply an offset if the high part of the 32bit vector was selected,
and then divide the result by 2 to account for vector expansion.
To sum-up, swizzling on midgard is complicated, and I'm not sure I got
it right, but it seems to print what I expect on the few compute
shaders using 64bit arithmetic I debugged.

Even though 8-bit ALUs are not supported, we can have [un]pack_32_4x8
instructions which translate to IMOVs, and those operate on 8-bit
vectors. The problem is, the swizzling granularity is 16 bit, which
means we don't support
MOV.i8 R0.xyzw, TMP0.xxxx, R1.zyxw
and the compiler doesn't even complain, it just applies 8 bit
swizzling directly, which obviously doesn't work.
This is probably not the right way to fix that, but I thought I'd
raised the issue with a hack to fix, so we can get the discussion
started.

The register allocator assumes instructions are executed sequentially
and allows one instruction to overwrite a portion of a register written
by a previous instruction if this portion is never used. But scalar and
vector ALUs might be executed in parallel if they are part of the same
bundle, and when such instructions write to the same portion of the
register file, the result is undefined.
Let's add intra-bundle interferences to avoid this situation.

The bug here is that the DRI context "flags" are intended to alias the
GLX context flag values, and they don't, DRI's no-error flag is GLX's
reset-isolation flag. GLX (and EGL!) treat no-error as a context
attribute, and reset isolation predates Mesa's no-error implementation
by several years. The GL_KHR_no_error spec does describe it as a
"context flag", though, so maybe that's why we do it as a (DRI) context
flag.
In order to unalias these we need a new contract with the loader. We
remove the old __DRI_NO_ERROR extension, and add a new
__DRI_RENDERER_HAS_CONTEXT_NO_ERROR value to query. Loaders can key on
that to know to pass no-error-ness through as a context attribute,
matching the GLX/EGL calling convention. We go ahead and define
__DRI_CTX_FLAG_RESET_ISOLATION as well, and update the drivers to refuse
it since we don't support it yet.
This means mismatched drivers/loaders will not be able to create
no-error contexts. Too bad. If you want performance that badly you can
build both things at once.

Meson devenv is a feature added in meson 0.58 (thus the features is
version guarded) that allows creating a shell environment with
environment variables automatically setup for running the project inside
the build dir. Some variables (such as LD_LIBRARY_PATH and PATH) are set
automatically, others must be added by the project.
For vulkan is is relativley simple, we create a new, uninstalled, icd
file for each driver and set the VK_ICD_FILENAMES variable
appropriately. This can be used with:
```sh
meson devenv -C $builddir
```
then, vulkan applications will automatically use the uninstall vulkan
driver, no need to install.
