If a nir_variable is tagged with per_view, it must be an array with
size corresponding to the number of views. For slot-tracking, it is
considered to take just the slot for a single element -- drivers will
take care of expanding this appropriately.
This will be used to implement the ability of having per-view position
in a vertex shader in Intel platforms.

This will help upcoming C++ code that will have to combine those two
semantics. In C++ it is not possible to do this without a cast or
adding an operator| to the enum. Since having the short form will
also be convient to C, we picked the former solution.

To facilitate lowering SSBOs to globals, we need a load_ssbo_address
intrinsic. This intrinsic takes an SSBO index and loads the address in
global memory of the SSBO (likely implemented via a uniform in the
driver). In the future, we'll support bounds checking, but at the moment
this is not supported (this pass should only be used for trusted
contexts at the moment, i.e. contexts without robustness extensions).

Add a pointer_initializer field to nir_variable analogous to
constant_initializer, which can be used to initialize the nir_variable
to a pointer to another nir_variable. Just like the
constant_initializer, the pointer_initializer gets eliminated in the
nir_lower_constant_initializers pass.

This means you can directly use format utils on it without having to have
your own GL enum to number-of-components switch statement (or whatever) in
your vulkan backend.
Thanks to imirkin for fixing up the nouveau driver (and a couple of core
details).
This fixes the computed qualifiers for EXT_shader_image_load_store's
non-integer sizeNxM qualifiers, which we don't have tests for.

This introduces:
- nir_texop_fragment_mask_fetch (fetch a fragment mask from a
compressed multisampled color surface)
- nir_texop_fragment_fetch (fetch a color fragment for a
particular sample at corresponding fragment mask index).
These two texture operations are necessary for implementing
SPV_AMD_shader_fragment_mask.

This introduces new vec8 and vec16 instructions (which are the only
instructions taking more than 4 sources), in order to construct 8 and 16
component vectors.
In order to avoid fixing up the non-autogenerated nir_build_alu() sites
and making them pass 16 src args for the benefit of the two instructions
that take more than 4 srcs (ie vec8 and vec16), nir_build_alu() is has
nir_build_alu_tail() split out and re-used by nir_build_alu2() (which is
used for the > 4 src args case).
v2 (Karol Herbst):
use nir_build_alu2 for vec8 and vec16
use python's array multiplication syntax
add nir_op_vec helper
simplify nir_vec
nir_build_alu_tail -> nir_builder_alu_instr_finish_and_insert

This is similar to a scheduler I've written for vc4 and i965, but this
time written at the NIR level so that hopefully it's reusable. A notable
new feature it has is Goodman/Hsu's heuristic of "once we've started
processing the uses of a value, prioritize processing the rest of their
uses", which should help avoid the heuristic otherwise making such
systematically bad choices around getting texture results consumed.
