chain->base.present_mode is unset at this point, ie. it's
zero-initialized. VK_PRESENT_MODE_IMMEDIATE_KHR happens to be 0,
so the WSI will attempt to use tearing-control on compositors that
don't support it.

Kernel makes every mapping coherent. If a memory type is truly
incoherent, it's better to remove the host-visible flag than silently
making it coherent. However, for app compatibility purpose, when
coherent-cached memory type is unavailable, we emulate the first cached
memory type with the first coherent memory type.

Have to set the interlaced field of the surface before
end_frame is called in the pipe codec object so the info
is available to the frontend/va, instead of setting it
directly in end_frame like before.

Restore transfer box original size after temporal per plane
dimension calculation.
Currently the returned transfer object on Map will have the
size (usually downsampled) of the latest plane instead of
the overall resource size. Then on unmap, when flushing the
changes the received transfer box has the wrong dimensions
and only partial data is flushed.

With lavapipe the previous change to only enable the hack when there's
no textures bound doesn't work anymore, since we don't have that
information when using the texture handles.
So add another random state restriction which is sufficient to pass
tests. (This really needs a better long term solution.)

Huge thanks to Tapani Pälli for debugging this issue, figuring out
what was going wrong, proposing fixes, and walking me through where
things were going off the rails.
BLORP always disables tessellation and geometry shaders. Our handling
tried to look at ice->shaders.uncompiled[] to determine whether the next
draw needed those shaders. If not, we can leave BLORP's residual state
that disabled those stages in place, and skip looking at it.
Unfortunately, predicting the future is a bit fraught, in part due to
the uncompiled[] and prog[] arrays being slightly out of sync at times.
Consider the following case:
1. Draw with tessellation shaders in place
=> uncompiled[TES] and prog[TES] will both point at valid shaders.
2. Gallium calls pipe->bind_tes_state(NULL).
=> This makes uncompiled[TES] point at NULL, and flags
IRIS_STAGE_DIRTY_UNCOMPILED_TES.
Because iris_update_compiled_shaders() hasn't happened yet,
uncompiled[TES] is NULL but prog[TES] has the stale TES from
the previous draw still.
3. BLORP operations happen
=> BLORP sees uncompiled[TES] == NULL and decides that tessellation
is off for the upcoming draws. So it skips flagging tess state.
4. Gallium calls pipe->bind_tes_state(shader from step #1).
=> uncompiled[TES] points at the original shader.
IRIS_STAGE_DIRTY_UNCOMPILED_TES gets flagged again.
5. Draw again
=> This calls iris_update_compiled_shaders(), which sees that
a TES is bound, and calls iris_update_compiled_tes(). But
because the same shader was bound as before, the program it
comes up with is identical to the one already bound at
ice->shaders.prog[TES]. So, it thinks it doesn't have to
flag any tessellation state dirty because it was already
set up for the last draw.
This random unbind and rebind between draws leads to a situation
where, at step #3, BLORP thinks it can skip flagging tessellation
state (nothing is bound), and at step #5, normal state handling
thinks it can skip flagging tessellation state (nothing changed
since last time). So nobody does, and things break.
This unbind appears to be happening when st_release_variants()
decides it wants to free some shaders. Then a rebind happens to
put back the actual shader for the draw. So, it's not theoretical.
To fix this, we change BLORP to look at ice->shaders.prog[] rather
than uncompiled[]. This is equivalent to thinking about the previous
draw, rather than the next. If the last draw had tessellation off,
then BLORP's disabling was a no-op, and the GPU is still in the same
state as the previous draw. This is more reliable than predicting
the future.
