The previous assertions required for texture sizes smaller than block_size
that src_box.x + src_box.width still be block size.
(e.g. for a texture with width 3, and src_box.x = 0, src_box.width would
have to be 4 to not assert.)
This caused some assertions with some other state tracker.
It looks though like callers aren't expected to round up widths to block sizes
(for sizes larger than block size the assertion would still have verified it
wouldn't have been rounded up) so we simply shouldn't use a minify which
rounds up to block size.

The gallium contract would be that bind flags must indicate all possible
bindings a resource might get used, but fact is the mesa state tracker does
not set bind flags correctly, and this is more or less unfixable due to GL.
This caused a bug with piglit arb_uniform_buffer_object-rendering-dsa
since 6e6fd911da - the commit is correct,
but it caused us to miss updates to fs UBOs completely, since the
corresponding buffer didn't have the appropriate bind flag set (thus we
wouldn't check if it is indeed currently bound).
See the discussion about this starting here:
https://lists.freedesktop.org/archives/mesa-dev/2016-June/119829.html
So, update the bind flags when we detect such usage.
Note we update this value for now only in places which matter for us - that
is creating sampler/surface view, or binding constant buffer. There's plenty
more places (setting streamout buffers, vertex/index buffers, ...) where
things can be set with the wrong bind flags, but the bind flags there never
matter.
While here also make sure we only set dirty constant bit when it's a fs
constant buffer - totally doesn't matter if it's vs/gs.

The images struct is an uninitialized local variable on the stack. If the
callback returns 0, the struct might not have been updated and so should
be considered uninitialized. Currently the code ignores the return value,
which (depending on stack contents) might end up in reading a non-zero
value from images.image_mask and dereferencing further fields.
Another solution would be to initialize image_mask with 0, but checking
the return value seems more sensible and it is what Gallium is doing.

I haven't found any mention of this in the hardware docs, but
experimentally what seems to be going on is that when the per-thread
scratch slot size is changed between two pipelined draw calls, shader
invocations using the old and new scratch size setting may end up
being executed in parallel, causing their scratch offset calculations
to be based in a different partitioning of the scratch space, which
can cause their thread-local scratch space to overlap leading to
cross-thread scratch corruption.
I've been experimenting with alternative workarounds, like emitting a
PIPE_CONTROL with DC flush and CS stall between draw (or dispatch
compute) calls using different per-thread scratch allocation settings,
or avoiding reuse of the scratch BO if the per-thread scratch
allocation doesn't exactly match the original. Both seem to be as
effective as this workaround, but they have potential performance
implications, while this should be basically for free.
Fixes over 40 failures in our CI system with spilling forced on
(including CTS, dEQP and Piglit failures) on a number of different
platforms from Gen4 to Gen9. The 'glsl-max-varyings' piglit test
seems to be able to reproduce this bug consistently in the vertex
shader on at least Gen4, Gen8 and Gen9 with spilling forced on.
