For reference picture sets, there are cases that rps will not always
be used. Once detect the unused flag from encoded bitstream, we should
not add this rps to any list, otherwise pass the incorrect reference
and skip the correct rps.

It will fix the corruption for frame, that only has one stort term ref
picture set, we set NULL rps for this case previously, causing taking
incorrect reference. Instead we should take that only short term set
as reference

The video size from format container is not always compatible with
the size from codec bitstream, the HW decoder should take the size
information from bitstream, otherwise the corruption appears with clip
that has different size info between bitstream and format container
So we are passing width(height)_in_samples from sequence parameter
set to video decoder.

This changes the order of basic blocks to be equal to the order of code in the
original TGSI, which is nice for making sense of shader dumps.

Some of the existing code is needlessly complicated. The basic principle
should be: control-flow opcodes emit branches to properly terminate the
current block, _unless_ the current block already has a terminator (which
happens if and only if there was a BRK or CONT).
This also fixes a bug where multiple terminators were created in a block.

In core profile, we support up to 16 viewports. However, in the
majority of cases, only 1 of them is actually used - we only need
the others if the last shader stage prior to the rasterizer writes
gl_ViewportIndex.
Processing all 16 viewports adds additional CPU overhead, which hurts
CPU-intensive workloads such as Glamor. This meant that switching to
core profile actually penalized Glamor to an extent, which is
unfortunate.
This patch tracks the number of relevant viewports, switching between
1 and ctx->Const.MaxViewports if gl_ViewportIndex is written. A new
BRW_NEW_VIEWPORT_COUNT flag tracks this. This could mean re-emitting
viewport state when switching, but hopefully this is offset by doing
1/16th of the work in the common case. The new flag is also lighter
weight than BRW_NEW_VUE_MAP_GEOM_OUT, which we were using in one case.
According to Eric Anholt, x11perf -copypixwin10 performance improves by

Previously, we were saving off the last nir_block in a vtn_block before
moving on so that we could find the nir_block again when it came time to
handle phi sources. Unfortunately, NIR's control flow modification code is
inconsistent when it comes to how it splits blocks so the block pointer we
saved off may point to a block somewhere else in the shader by the time we
get around to handling phi sources. In order to get around this, we insert
a nop instruction and use that as the logical end of our block. Since the
control flow manipulation code respects instructions, the nop will keeps
its place like any other instruction and we can easily find the end of our
block when we need it.
This fixes a bug triggered by a couple of vkQuake shaders.

This intrinsic has no destination, no sources, no variables, and can be
eliminated. In other words, it does nothing and will always get deleted by
dead code elimination. However, it does provide a quick-and-easy way to
temporarily tag a particular location in a NIR shader.
