This simplifies our deref handling by emitting the actual NIR deref
instructions on-the-fly instead of of building up a deref chain and then
emitting them at the last moment. In order for this to work with the
parts of the compiler that assume they can chase deref chains, we have
to run nir_rematerialize_derefs_in_use_blocks_impl to put the derefs
back in the right places. Otherwise, in cases such as loop continues
where the SPIR-V blocks are not in the same order as the NIR blocks, we
may end up with a deref chain with a parent that does not dominate it's
child and nir_repair_ssa_impl will insert phis in the deref chain.

The loop through instructions doesn't set the cursor for us so unless we
set it somewhere, we may end up emitting instructions in the wrong
place. The only reason why we haven't been bitten by this in the past
is that it only happens in a few variable pointers cases and the CTS
tests for those don't use much control flow so things were getting
emitted in the correct order by accident.

These days, we have two sampler lowering passes. The newer one,
gl_nir_lower_samplers_as_deref, is used by radeonsi. It rewrites
variables to drop structures out of sampler deref chains, to make
life simpler. It then sets var->data.binding for non-bindless
sampler and image variables based on the GL uniform storage's
opaque index values.
The older one converts sampler deref chains (nir_tex_src_texture_deref)
to a numerical offset (nir_tex_src_texture_offset). It also stores the
constant-valued portion of that number in tex->texture_index, making
life really simple for drivers that don't support indirects. It too
pokes at GL uniform storage's opaque index values.
Logically, we can do the first pass (simplify derefs, set bindings)
then the second (turn derefs to offsets, set texture_index). This
patch does exactly that, eliminating some redundancy (only one pass
has to poke at GL uniform storage), and gaining proper var->data.binding
values for drivers using the full lowering.

We recurse to remove structures, and at each step, re-modify the
resulting type for our link in the deref chain. For arrays, the
result of recursion is the new underlying type - so we wrap it with
the array dimensionality again. For structs, we want to simply use
the new underlying type, skipping the struct altogether.
The correct way to do this is to do nothing at all. Previously, we
had reset type to next->type, which is the /old/ field type, not the
new field type we obtained by recursing. This undid our recursive work.
Fixes about 338 tests with nested structs, such as:
dEQP-GLES2.functional.uniform_api.value.initial.get_uniform.nested_structs_arrays.sampler2D_samplerCube_fragment
Note that currently only radeonsi uses this pass, and NIR support is
disabled there by default, so the breakage was likely not seen by most
people. The next commit uses this pass for more drivers, so this fix
prevents regressions from that change.

We do the ImageFormatProperties check already, and rejecting an usage
flag when both ImageFormatProperties and the WSI (which is Android)
support it is not allowed.
Intel does support storage for some of the support WSI formats, such
as R8G8B8A8_UNORM, and looking at the ISL_SURF_USAGE_DISABLE_AUX_BIT,
the imported images do not have any form of compression that would
prevent this fix.

The functional change here is moving the nir_lower_io_to_scalar_early()
calls inside st_nir_link_shaders() and moving the st_nir_opts() call
after the call to nir_lower_io_arrays_to_elements().
This fixes a bug with the following piglit test due to the current code
not cleaning up dead code after we lower arrays. This was causing an
assert in the new duplicate varyings link time opt introduced in
70be9afccb23.
tests/spec/glsl-1.10/execution/vsfs-unused-array-member.shader_test

In 92eb5bbc68d7324 we attempted to avoid copying clear colors whenever
we weren't doing a resolve. However, this broke MSAA resolves because
we need the clear color in the source. This patch makes blorp much more
conservative such that it only avoids the clear color copy if either
aux_usage == NONE or it's explicitly doing a fast-clear.

Even with the previous commit, hangs are still happening. The problem
there is that the VF cache invalidate do happen immediately without
waiting for previous rendering to complete. What happens is that we
invalidate the cache the moment the PIPE_CONTROL is parsed but we
still have old rendering in the pipe which continues to pull data into
the cache with the old high address bits. The later rendering with the
new high address bits then doesn't have the clean cache that it
expects/needs.

If we hit the memcpy() path for copy_region(), that will try to do a
transfer_map(), which goes badly for blits to/from staging triggered
by transfer_map() or transfer_unmap().
We could possibly add fd_blit2() which has allow_transfer_map param,
and call that for staging blits. But I'm not really sure if trying
the blit via copy_region() is very useful. At least for newer gens
that implement fd_context::blit(), it probably isn't.

Instead rework the API to push the fallback back to core code, so that
we can rework resource_copy_region() to have it's own fallback path,

This also makes ctx->blit() optional, and cleans up some unnecessary
callers.
