The vmwgfx driver supports emulated coherent surface memory as of version
2.16. Add en environtment variable to enable this functionality for
texture- and buffer maps: SVGA_FORCE_COHERENT.
This environment variable should be used for testing only.

In order to be able to add access modes to a pb_validate_entry, update
the pb_validate_add_buffer function to take a pointer hash table and also
to return whether the buffer was already on the validate list.
Update the svga winsys accordingly.

The rendered-to flag indicates that the HW surface content is more recent

SVGA_RELOC_INTERNAL indicates a transfer between surface and backing mob.
This means that if the GPU for example reads from the surface it writes
to the backing mob. But since the buffer mapping code allows for
simultaneous gpu- and cpu read access, a read from the surface to the mob
will not synchronize a subsequent map to the readback.
Fix this by inverting the mob access mode in a surface relocation with
SVGA_RELOC_INTERNAL set.

Instead unconditionally call SVGA3D_InvalidateGBSurface() since it's needed
also for Linux for dirty buffers and operation without SurfaceDMA.
For non-guest-backed operation, remove the surface cache surface invalidation
altogether.

This reverts commit 865b9ddae4.
The buffer always reports format PIPE_FORMAT_R8_UNORM so with this patch only
one component would be supported. The original issue is still relevant, but
the fix should be different.

Don't attempt sampling with HiZ if the sampler lacks support for it. On
ICL, the HW docs state that sampling with HiZ is not supported and that
instances of AUX_HIZ in the RENDER_SURFACE_STATE object will be
interpreted as AUX_NONE.

If the SSA def produced by this instruction is only in the block in
which it is defined and is not used by ifs or phis, then we don't have
a reason to convert it to a register in
nir_lower_ssa_defs_to_regs_block().
The special case for derefs is covered by the general case, so can be
removed: at this point all derefs in the block are
materialized (i.e. the whole deref chain is in the block) and derefs
are not used in phis.
v2: Fix wrong check for if_uses. If there's such an use, the def is
not "local_to_block". (Jason)

Normally gl_nir_lower_samplers_as_deref records info->textures_used
for us, but this pass runs after that, attempting to assign samplers
in the same order as st_atom_texture's external_samplers_used loop
so the stars align and we get the same locations.
Since we're adding textures late, we need to amend info->textures_used.
iris uses info->textures_used to set up texture bindings; this fixes
Piglit's ext_image_dma_buf_import-sample-{nv12,yuv420,yvu420} there.

First, allow the case for negative powers of two. Then ensure that we
use the absolute value of the non-constant value to calculate the
quotient -- this was hinted in the code by the name 'uq'.
This fixes an issue when 'd' is positive and 'n' is negative. The
ishr will propagate the negative sign and we'll use nir_ineg() again,
incorrectly.
v2: First version used only ishr, but that isn't sufficient, since it
never can produce a zero as a result. (Jason)
