intel/fs/gen11+: Handle ROR/ROL in lower_simd_width().

Prevents invalid code from being emitted for ROR/ROL instructions in
SIMD32 shaders.

The problem can be reproduced with the following tests while forcing
SIMD32 to be used for fragment shaders:

 piglit.shaders.glsl-rotate-left
 piglit.shaders.glsl-rotate-right

However the issue could occur in production already with compute
shaders and a workgroup size large enough to trigger SIMD32 dispatch.

glsl: Fix software 64-bit integer to 32-bit float conversions.

The current implementation was broken for any integers between 2^24
and 2^30 (it would return zero for me on ICL).  The reason is that for
such integers we wouldn't take the 'if (0 <= shiftCount)' early return
path, however 'shiftCount + 7' would be positive, leading to a
negative 'count' argument passed to __shift64RightJamming(), which
would give undefined results.

This reworks the affected conversion functions to use either
__shortShift64Left() or __shift64RightJamming() based on the sign of
the final shift count, which should avoid the problem.  In addition
this should qualify as a clean-up/optimization -- This implementation
of the conversion functions translates to 7 instructions less than the
original on Intel hardware.

This fixes the 'KHR-GL46.shader_ballot_tests.ShaderBallotFunctionBallot'
conformance tests on soft fp64 hardware with large enough subgroup
size (>16).

radv: Emit a BATCH_BREAK when changing pixel shaders or CB_TARGET_MASK.

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,
  but likely does an internal break on any descriptor set changes
  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
  should really be doing a FLUSH_DFSM).
- 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.
- Also emitting the existing break on framebuffer change when DFSM is
  disabled does not fix the issue.

st/mesa: Lower vars to ssa and constant prop before gl_nir_lower_buffers

The gl_nir_lower_buffers pass relies on recognizing the same literal
constants as the GLSL compiler so that constant buffer array indices
are constant in nir as well.  Without this, get_block_array_index()
would see

  vec1 32 ssa_723 = deref_var &const_temp@1 (function_temp int)
  vec1 32 ssa_724 = load_const (0x00000001 /* 0.000000 */)

  vec1 32 ssa_7 = deref_var &blockB (ssbo BlockB[1])
  vec1 32 ssa_8 = deref_array &(*ssa_7)[ssa_6] (ssbo BlockB) /* &blockB[ssa_6] */

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.

In most cases we would have dealt with this in the call to
st_nir_opts() in st_nir_link_shaders(), but in the num_shaders == 1
case (for example, compute) we would call gl_nir_lower_buffers()
before we lowered GLSL constants.  Move that corner case up next to
where we call st_nir_link_shaders() so we call st_nir_opts() at the
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];
 out vec4 color;
 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:
Failed to find the block by name "SSBO[0]"
