With SWTNL and index translation we're mapping buffers for reading. These
buffers are commonly upload_mgr buffers that might already be referenced
by another submitted or unsubmitted GPU command. A synchronous map will
then trigger a flush and sync, at least on Linux that doesn't distinguish
between read- and write referencing. So map these buffers async. If they
for some obscure reason happen to be dirty (stream-output, buffer-copy),
the resource_buffer code will read-back and sync anyway. For persistent /
coherent buffers a corresponding read-back and sync will happen in the
kernel fault handler.
Testing: Piglit quick. No regressions.

In the case of SWTNL and index translation we were uploading index buffers
and then reading out from them using the CPU. Furthermore, when translating
indices we often cached the results with an upload_mgr buffer, causing the
cached indexes to be immediately discarded on the next write to that
upload_mgr buffer.
Fix this by only uploading when we know the index buffer is going to be
used by hardware. If translating, only cache translated indices if the
original buffer was not a user buffer. In the latter case when we're not
caching, use an upload_mgr buffer for the hardware indices.
This means we can also remove the SWTNL hand-crafted index buffer upload
mechanism in favour of the upload_mgr.
Finally avoid using util_upload_index_buffer(). It wastes index buffer
space by trying to make sure that the offset of the indices in the
upload_mgr buffer is larger or equal to the position of the indices in
the source buffer. From what I can tell, the SVGA device does not
require that.
Testing done: Piglit quick. No regressions.

For the block BLOCK_TEXEL_VIEW_COMPATIBLE case, this didn't matter
because the flags were already more-or-less what we wanted. However,
for gen7 stencil shadow images, it still had ISL_SURF_USAGE_STENCIL_BIT
so we were getting W-tiled which isn't what we want for the shadow. By
passing just ISL_SURF_USAGE_TEXTURE_BIT (and CUBE if we care), we now
get something that's actually texturable.
Fixes: f3ea0cf828 "anv: Add stencil texturing support for gen7"
Copies to a shadow image happen during a VkCmdPipelineBarrier or at
subpass transitions. We could potentially be a bit more conservative
but these transitions shouldn't happen often and it's better to have our
bases covered.

Most places in NIR, we treat matrices like arrays. The one annoying
exception to this has been nir_constant where a matrix is a first-class
thing. This commit changes that so a matrix nir_constant is the same as
an array nir_constant. This makes matrix nir_constants a tiny bit more
expensive but shrinks all others by 96B.

Even if only variables access flags are changed, the existing NIR
infrastructure expects metadata to be explicitly preserved, so do
that. Don't care about avoiding preserve to be called twice since the
cost is negligible.
This scenario can be triggered by dead variables, and also by other
intrinsics that read the variables -- but not cause progress to be
made when processing the intrinsics.

Right now, this just deduces when we can arbitrarily reorder SSBO and
image loads, matching the existing logic in radeonsi's TGSI->LLVM pass.
This approach can't handle some things that nir_opt_copy_prop_vars can,
but it can handle images, and with GCM it lets us hoist reads outside of
loops. We can also pass this information to LLVM which lets it do its
own optimizations on it.
This is GLSL only as I haven't tested it on Vulkan yet, and it would
probably need a few changes to work there.
