When building with asserts enabled, we'll end up triggering an assert
in pipe_buffer_map_range down this code-path, due to trying to map
an empty range. Even if we avoid that, we'll trigger another assert
a bit later, because u_vbuf_get_minmax_index returns a min-index of
-1 here, which gets promoted to an unsigned value, and gives us an
out-of-bounds buffer-mapping offset.
Since we can't really have a well-defined min/max range here when
the range is empty anyway, we should just drop this dance in the
first place. After all, no rendering is going to be produced.
This fixes a crash in dEQP-GLES31.functional.draw_indirect.random.0
on VirGL for me.

After performing a fast-clear eliminate, a FMASK decompress,
or a DCC decompress, we can reset the predicate to FALSE.
With that, the GPU should be able to skip unnecessary color
decompression passes.

Performing a DCC decompression pass is currently pretty rare,

Use caps to obtain the multisample sample positions for up to 16
positions and implement the according Gallium interface.
This implemenation (plus its counterpart in virglrenderer) assume that
the fixed sample position are always the same for a given number of samples
over the whole live time of a qemu session. It also assumes that sample
series are only given for 2, 4, 8, and 16 samples, and for intermediate
numbers N of samples the next higher supported set from above list is picked
and the sample positions for the first N samples are returned accordingly.

v2: remove unrelated chunk (thanks Ilia Mirkin)

- fix unused varible warning
- update description
v4: explain better what this patch assumes and how it handles sample numbers

and PIPE_FORMAT_R8G8B8A8_SRGB, as well.
The reason for this is that when Virgl runs with GLES on the host, it
cannot directly upload textures in BGRA.
So to avoid a conversion step, consider the RGB sRGB formats as well for
this extension.

If the driver doesn't support PIPE_FORMAT_B8G8R8A8_SRGB, fall back to
PIPE_FORMAT_R8G8B8A8_SRGB.
Drivers such as Virgl will have a hard time supporting
PIPE_FORMAT_B8G8R8A8_SRGB when the host runs GLES, as GL_BGRA isn't as
well suported there.
So go with PIPE_FORMAT_R8G8B8A8_SRGB so these drivers can avoid a
conversion copy.
v2: Fix typo in commit message

When Mesa itself implements ETC2 decompression, it currently
decompresses to formats in the GL_BGRA component order.
That can be problematic for drivers which cannot upload the texture data
as GL_BGRA, such as Virgl when it's backed by GLES on the host.
So this commit adds a flag to _mesa_unpack_etc2_format so callers can
specify the optimal component order.
In Gallium's case, it will be requested if the format isn't in
PIPE_FORMAT_B8G8R8A8_SRGB format.
For i965, it will remain GL_BGRA, as before.

We need to add loop terminators to the list in the order we come
across them otherwise if two or more have the same exit condition
we will select that last one rather than the first one even though
its unreachable.
This fix is for simple unrolls where we only have a single exit
point. When unrolling these type of loops the unreachable
terminators and their unreachable branch are removed prior to
unrolling. Because of the logic change we also switch some
list access in the complex unrolling logic to avoid breakage.

We were overlapping it with the threadable/nan flags, resulting in
incorrect relocations (threadable/nan included in the offset) and wrong
ordering in the CLIF files.
The XML ends up noisier if you're only looking at one version, but from
the diffstat there's obvious wins in terms of deduplication. This will
get even more significant if we ever support 3.2 or 4.0.
The XML zipper wants one XML per version for filling out its tables, but
we want to do more than one GPU version per XML now. Assume that the
"gen" field will be the same as min_ver and look up our XML text assuming
that they're listed in increasing min_ver.
