This prints a log of every PIPE_CONTROL flush we emit, noting which bits
were set, and also the reason for the flush. That way we can see which
are caused by hardware workarounds, render-to-texture, buffer updates,
and so on. It should make it easier to determine whether we're doing
too many flushes and why.
Looking at the scissor, we can discard some tiles. We specifially don't
care about the scissor on the wallpaper, since that's a no-op if the
entire tile is culled.

Panfrost's tiling routines (incorrectly) ignored the source stride,
masking this bug; lima's routines respect this stride, causing issues
when tiling NPOT textures whose stride is not a multiple of 64
(for instance, NPOT textures with bpp=1).

We can rely on only one kind of synchronization object (drm-syncobj)

use in our implementation.

This basically boils down to supporting persistent and coherent buffer
storage.
We chose to use coherent buffer storage for all persistent buffers
even if it's not explicitly specified, since using glMemoryBarrier to
obtain coherency would be particularly expensive in our driver stack,
and require a lot of additional bookkeeping.

With SWTNL and index translation we're mapping buffers for reading. These
buffers are commonly upload_mgr buffers that might already be referenced
by another submitted or unsubmitted GPU command. A synchronous map will
then trigger a flush and sync, at least on Linux that doesn't distinguish
between read- and write referencing. So map these buffers async. If they
for some obscure reason happen to be dirty (stream-output, buffer-copy),
the resource_buffer code will read-back and sync anyway. For persistent /
coherent buffers a corresponding read-back and sync will happen in the
kernel fault handler.
Testing: Piglit quick. No regressions.

In the case of SWTNL and index translation we were uploading index buffers
and then reading out from them using the CPU. Furthermore, when translating
indices we often cached the results with an upload_mgr buffer, causing the
cached indexes to be immediately discarded on the next write to that
upload_mgr buffer.
Fix this by only uploading when we know the index buffer is going to be
used by hardware. If translating, only cache translated indices if the
original buffer was not a user buffer. In the latter case when we're not
caching, use an upload_mgr buffer for the hardware indices.
This means we can also remove the SWTNL hand-crafted index buffer upload
mechanism in favour of the upload_mgr.
Finally avoid using util_upload_index_buffer(). It wastes index buffer
space by trying to make sure that the offset of the indices in the
upload_mgr buffer is larger or equal to the position of the indices in
the source buffer. From what I can tell, the SVGA device does not
require that.
Testing done: Piglit quick. No regressions.
