ACO doesn't create a waitcnt for barriers between texture samples and

We also have use a larger memory scope to avoid an ACO optimization.

GFX8 is still restricted to linear tiling because it's not yet clear

util_format_get_blocksize asserts that the blocksize isn't zero.
However the blocksize will be zero if the format's channel encoding
is unspecified. The channel encoding is only meaningful for the
plain u_format layout, so util_format_get_blocksize can't be used
for formats with another layout. For example, YUV formats don't have
the channel encoding specified.
Use util_format_get_blocksizebits, which just returns zero without
an assertion for formats which don't have a channel encoding.

Late export is theoretically better if used with LATE_ALLOC,
but in practice, the early export has an advantage of
lower register usage, therefore more concurrent waves.
The idea of this commit is that "small" shaders benefit from early
primitive export more, due to being able to launch much more waves.
Let's consider a NIR shader "small" when it has only 1 block.
This yields both better performance, and better stats, than always
using late export.
