Since 1285f71d3e landed, it needs to provide apps with proper sample
position for MSAA.
Currently no way to query this to hw, these are taken from blob driver.

Noticed that with webgl (in chromium, at least) we end up generating a
lot of no-op submits just to get a fence. Tracking the last fence and
returning that if there is no rendering since last flush avoids this.

These are not necessary because the corresponding settings are set via
the .dir-locals.el file anyway. Most of them were missing a ‘:’ after
“tab-width” which was making Emacs display an annoying warning
whenever you open the file.
This patch was made with:
sed -ri '/-\*- mode:/,/^$/d' \
$(find src/gallium/{drivers,winsys} -name \*.\[ch\] \
-exec grep -l -- '-\*- mode:' {} \+)

u_transfer_helper already had code to handle treating packed Z32_S8
as separate Z32_FLOAT and S8_UINT resources, since some drivers can't
handle that interleaved format natively.
Other hardware needs depth and stencil as separate resources for all
formats. For example, V3D3 needs this for 24-bit depth as well.
This patch adds a new flag to lower all depth/stencils formats, and
implements support for Z24_UNORM_S8_UINT. (S8_UINT_Z24_UNORM is left
as an exercise to the reader, preferably someone who has access to a
machine that uses that format.)

In c3d9f29b we allowed ctx->batch to be null, and started tracking the
current framebuffer state in fd_context. But the existing logic in
fd_blitter_pipe_begin() would, if !ctx->batch, set null fb state to be
restored after blit. Which broke the world of deqp (and probably other
things)

This adds a freedreno backend for the a6xx generation GPUs, which at
the time of this commit is about 98% GLES2 conformant. Much remains to
be done - both performance work and feature work towards more recent
GLES versions, but this is a good start.

Overall a nice 5-10% gain for most games. And more for things like
glmark2 texture benchmark.
There are some rough edges. In particular, the hardware seems to only
support tiling or component swap. (Ie. from hw PoV, ARGB/ABGR/RGBA/
BGRA are all the same format but with different component swap.) For
tiled formats, only ARGB is possible. This isn't a big problem for
*sampling* since we also have swizzle state there (and since
util_format_compose_swizzles() already takes into account the component
order, we didn't use COLOR_SWAP for sampling). But it is a problem if
you try to render to a tiled BGRA (for example) surface.
The next patch introduces a workaround for blitter, so we can generate
tiled textures in ABGR/RGBA/BGRA, but that doesn't help the render-
target case. To handle that, I think we'd need to keep track that the
tiled format is different from the linear format, which seems like it
would get extra fun with sampler views/etc.
So for now, disabled by default, enable with FD_MESA_DEBUG=ttile. In
practice it works fine for all the games I've tried, but makes piglit
grumpy.

The rules are sufficiently different for a5xx with tiled textures, so
split this out into something that can be implemented per-generation.
The a5xx specific implementation will come in a later patch.

In the busy && !needs_flush case, we can support a DISCARD_RANGE upload
using a staging buffer. This is a bit different from the case of mid-
batch uploads which require us to shadow the whole resource (because
later draws in an earlier tile happen before earlier draws in a later
tile).

ctx->last_fence isn't such a terribly clever idea, if batches can be
flushed out of order. Instead, each batch now holds a fence, which is
created before the batch is flushed (useful for next patch), that later
gets populated after the batch is actually flushed.

In transfer_map(), when we need to flush batches that read from a
resource, we should be holding screen->lock to guard against race
conditions. Somehow deferred flush seems to make this existing
race more obvious.

To enable per-context priorities, we need to have per-context pipe's.
Unfortunately we still need to keep the global screen pipe, mostly just
for screen->get_timestamp().

Similar to the way width/pitch alignment works, it seems like we need to
do similar for height. Otherwise the BLIT from system memory to GMEM
can over-fetch beyond the end of the buffer, triggering a fault.
I'm not sure if there is a better solution yet. Possibly we could fall
back to pre-a5xx style DRAW packets for cases where BLIT might over-
fetch. (We in theory have that problem already with rendering to higher
mipmap levels, although fortunately those tend to use GMEM bypass.)
This fixes issues reported with glamor.

pipe_draw_info::indexed is replaced with index_size. index_size == 0 means
non-indexed.
Instead of pipe_index_buffer::offset, pipe_draw_info::start is used.
For indexed indirect draws, pipe_draw_info::start is added to the indirect
start. This is the only case when "start" affects indirect draws.
pipe_draw_info::index is a union. Use either index::resource or
index::user depending on the value of pipe_draw_info::has_user_indices.
v2: fixes for nine, svga
It is always the draw ring. Except for a5xx queries like time-elapsed,
where we will eventually want to emit cmds into both binning and draw

For a5xx (and actually some queries on a4xx) we can accumulate results
in the cmdstream, so we don't need this elaborate mechanism of tracking
per-tile query results. So make it into vfuncs so generation specific
backend can use it when it makes sense.

In particular, move per-shader-stage info out to a seperate array of
enum's indexed by shader stage. This will make it easier to add more
