We were treating count == 0 as the format not being supported at all,

I had missed that LDC actually uses vec4 units for its offset. This
means that we have to create a new instruction, and lower it in
ir3_nir_lower_io_offsets, similar to the existing SSBO instructions.
Unfortunately we can't assume that loads are always vec4-aligned, so we
have to use the alignment information that NIR gives us. Unfortunately,
it's currently woefully inadequate, and will have to be fixed to give us
good codegen in the future.

anv: Fix UBO range detection in anv_nir_compute_push_layout

This fixes two bugs:  First, if the same block index showed up twice, we
only pick the first one.  Second, we weren't multiplying by 32.  This
didn't show up in tests because RBA testing is garbage.  Found while
looking at shaders from the UE4 Shooter demo.

iris: make BATCH_SZ smaller by BATCH_RESERVED bytes

Iris allocates gem buffers using buckets of allocation sizes that are
page aligned. We always ask for batch buffers of size BATCH_SZ +
BATCH_RESERVED, which is not page aligned: we ask for 65552 bytes,
which ends up in the bucket of size 81920, resulting in 20% unused
space. Adjust things so there is no waste of space: BATCH_SZ +
BATCH_RESERVED is now 65536.

We assign a real value a few lines below, and none of the lines in
between rely on the zeroed bo->gtt_offset value.
