i965: Drop mark_surface_used mechanism.

The original idea was that the backend compiler could eliminate
surfaces, so we would have it mark which ones are actually used,
then shrink the binding table accordingly.  Unfortunately, it's a
pretty blunt mechanism - it can only prune things from the end,
not the middle - since we decide the layout before we even start
the backend compiler, and only limit the size.  It also basically
gives up if it sees indirect array access.

Besides, we do the vast majority of our surface elimination in NIR
anyway, not the backend - and I don't see that trend changing any
time soon.  Vulkan abandoned this plan a long time ago, and I don't

spirv: Whack sampler/image pointers to uniform

A long time in a galaxy far far away, there was a GLSLang bug with how
it handled samplers passed in as function parameters.  (The bug can be
found here: https://github.com/KhronosGroup/glslang/issues/179.)
Unfortunately, that version was shipped in several apps and has been
causing heartburn for our SPIR-V parser ever since.

Recent changes to NIR uncovered a moderately old bug in how we work
around this issue.  In particular, we ended up with a deref_cast from
uniform to local which is not a no-op cast so nir_opt_deref wasn't
getting rid of the cast.  The only reason why it worked before was
because someone just happened to call nir_fixup_deref_modes which
"fixed" the cast (that shouldn't be happening) and then a later round of
copy-prop would get rid of it.  The fact that the deref_cast survived
that long without causing trouble for other parts of NIR is a bit
surprising.

Just whacking the mode of the pointer seems to fix it fairly
unobtrusively.  Currently, only apps with this bug will have a local
variable containing an image or sampler.

blorp: Add blorp_get_surface_address to the driver interface.

Currently, BLORP expects drivers to provide two functions for dealing
with buffers: blorp_emit_reloc and blorp_surface_reloc.  Both record a
relocation and combine the BO address and offset into a full 64-bit

address to an implicitly-known buffer where surface states are stored.
(In contrast, blorp_emit_reloc returns the value.)

The upcoming Iris driver stores surface states in multiple buffers,
which makes it impossible for blorp_surface_reloc to write the combined
address - it only takes an offset, not the actual buffer to write to.

This commit adds a third function, blorp_get_surface_address, which
combines and returns an address, which is then passed to ISL's surface
state fill functions.  Softpin-only drivers can return a real address
here and skip writing it in blorp_surface_reloc.  Relocation-based
drivers are have options.  They can simply return 0 from the new
function, and continue writing the address from blorp_surface_reloc.
Or, they can return a presumed address from blorp_get_surface_address,
and have other relocation processing write the real value later.
