Fixes a hang on Raven with Resident Evil 2.

I did not find anything more restricted to fix it:

- Setting persistent_states_per_bin to 1 fixes it too,

  too.
- Only breaking the batch when cb_target_mask changes does not fix
  it (and looking at AMDVLK comments, I suspect the code in radeonsi

- Always doing a FLUSH_DFSM on shader switch helps, but that is more
  often than this and I don't think we should be doing that when DFSM
  is disabled.

instead of a literal 1, and ultimately generate the block name
BlockB[0].  That used to work, since we before the previous commits
we'd compact the block binding points and names. Thus, there would
always be a BlockB[0].

Now, if an entry in a block array isn't used, we don't generate that
block name, which means that if entry 0 isn't used BlockB[0] isn't
present and then get_block_array_index() fails to find the block.

before we lowered GLSL constants.  Move that corner case up next to

same point in the flow for all shaders.

glsl/nir: do not change an element index to have correct block name

When SSBO array is used with packed layout, both IR tree
and as a result, NIR tree will be incorrect.
In fact, the SSBO dereference indices won't
match the array size in some cases like the following:

"layout(packed, binding=1) buffer SSBO { vec4 a; } ssbo[3];

 void main() {
   color = ssbo[2].a;
 }"

After linking the IR and then NIR will have an SSBO array
definition with size 1 but dereference still will have index 2
and linked_shader->Program->sh.ShaderStorageBlocks
will contain just SSBO with name "SSBO[2]"

So this line should be removed at least as a workaround for now
to avoid error like:

iris: Disable ASTC 5x5 support on Gen9 for now.

Intel Gen9 hardware has some nasty restrictions where ASTC 5x5 formats
and color compression can't both live in the sampler cache at the same
time.  To properly support it, we have to track which of those exist
in the cache and flush ASTC out or resolve away compression.

As far as I'm aware, very little uses ASTC 5x5 textures, so instead
of replicating all that for iris, we simply turn it off and rely on
the Gallium fallback mechanism to fake it via uncompressed RGBA.

This should avoid GPU hangs any time people use ASTC 5x5 with CCS.
