This warning detects non-void functions with a missing return statement,
return statements with a value in void functions, and functions with an
bogus return type that ends up defaulting to int. It's already enabled
by default with -Wall. Generally, these are fairly serious bugs in the
code, which developers would like to notice and fix immediately. This
patch promotes it from a warning to an error, to help developers catch
such mistakes early.
I would not expect this warning to change much based on the compiler
version, so hopefully it won't become a problem for packagers/builders.
See the GCC documentation or 'man gcc' for more details:

Instead of having weak references to the anv functions and separate
trampoline functions with their own dispatch table, just make the
trampoline functions weak. This gets rid of a dispatch table and
potentially lets the compiler delete the unused weak function. The
end result is a reduction in the .text section of 5.7K and a reduction
in the .data section of 1.4K.

We don't need weak references to instance entrypoints because we never
have more than one of each so we don't need the NULL fall-back. This
also helps us avoid forgetting things because we now get link errors for
missing instance entrypoints.

This got missed during 1.1 enabling because it was defined as an
interaction between device groups and WSI and it wasn't obvious it was
in the delta.
The idea behind it is that it's supposed to provide a hint to the
application in a multi-GPU setup to indicate which regions of the screen
are being scanned out by which GPU so a multi-device split-screen
rendering application can render each part of the screen on the GPU that
will be presenting it and avoid extra bus traffic between GPUs. On a
single-GPU setup or one which doesn't support this present mode, we need
to do something. We choose to return the window size (or a max-size
rect) if the compositor, X server, or crtc is associated with the given
physical device and zero rectangles otherwise.

We already have wsi_device and we know the instance allocator at
wsi_device_init time so there's no need to pass it into the physical
device queries. This also fixes a memory allocation domain bug that can
occur if CreateSwapchain gets called prior to any queries (not likely)
in which case the cached connection gets allocated off the device
instead of the instance.

The number of immediate constants was fixed and the size check was
only done by means of an assertion. Given this a shader that emits
more immediate constants would result in a memory corruption when
mesa is build in release mode.
Instead of using this fixed limit allocate the space dynamically, let it
grow as needed, and also remove the unused ImmArray.

storing TCS inputs is a copy of the input arrays and allows
us to avoid copying all of the input data and then indirecting

Now that state which is different for draw vs binning pass is split out
into different state-groups with appropriate enable_mask (so the
appropriate one is chosen for draw vs binning), switch over to using a
single cmdstream for both passes.
This should significantly lower draw overhead for CPU bound benchmarks.

Prep work for a following patch, that introduces a cache to map from
program state (all shader stages) plus variant key to pre-baked hw
state (which could be emit'd via CP_SET_DRAW_STATE, for example).
To do that, we really want the variant key to be immutable, and to
treat the binning pass shader as an extra shader stage, rather than
as a VS variant.

Unfortunately gallium doesn't match what the hw wants perfectly here, in
using a separate CSO for each texture/sampler. So we have to use a hash
table to map the collection of texture/samplers to hw state object.
We probably could use separate hw state objects for texture and sampler
state, but mesa/st tends to update the tex and samp state together.

Eventually we want to move nearly everything, but no other state depends

For webgl aquarium, this reduces GPU load by about 10%, since for each
fish it does a uniform upload plus draw.. fish frequently are visible in
only a single tile, so this skips the uniform uploads for other tiles.
The additional step of avoiding WFI's when using CP_SET_DRAW_STATE seems
to be work an additional 10% gain for aquarium.
