Connor Abbott df955ce6b6 nir: Count i/o slots correctly for per-view variables 
This function wasn't counting driver slots correctly, resulting in
incorrect driver_location's and input_count. It seems intel doesn't use
this yet.

Connor Abbott ffe946d7e8 nir: Add nir_lower_multiview pass 
Taken mostly directly from the anv pass. A few anv-specific things that
I could leave in anv aren't included. Specifically on turnip we don't
need to set gl_Layer to 0, and we can handle the case where the FS reads
gl_ViewIndex, so that check is moved into anv.

Rhys Perry ee073cb543 nir/load_store_vectorize: improve vectorization with identical operations 
We might have several identical options to vectorize an entry with, but
only one might be vectorizable because of writes interfering.

An example of this is a pattern found in some CTS tests:
a = load(0)
b = load(4)
store(0, a)
store(4, b)
a = load(0)
b = load(4)
store(0, a)
store(4, b)
...

It might have attempted to vectorize the first load(0) with the second
load(4) without attempting the second load(4) when the first fails. This
changes vectorize_entries() to continue even if the first try_vectorize()
failed.

Intel has a separate pass for fusing FFMAs selectively.  We split
these flags in commit 1b72c31e1f and
the reasoning still stands.  The patch being reverted was just a
cleanup, so there should be no issue with reverting it.

Danylo Piliaiev f2b17dec12 nir/lower_samplers: Clamp out-of-bounds access to array of samplers 
Section 5.11 (Out-of-Bounds Accesses) of the GLSL 4.60 spec says:

"In the subsections described above for array, vector, matrix and
 structure accesses, any out-of-bounds access produced undefined
 behavior.... Out-of-bounds reads return undefined values, which
 include values from other variables of the active program or zero."

Robustness extensions suggest to return zero on out-of-bounds
accesses, however it's not applicable to the arrays of samplers,
so just clamp the index.

Otherwise instr->sampler_index or instr->texture_index would be out
of bounds, and they are used as an index to arrays of driver state.

E.g. this fixes such dereference:
 if (options->lower_tex_packing[tex->sampler_index] !=
in nir_lower_tex.c

  Out-of-bounds reads return undefined values, which

GL_KHR_robustness and GL_ARB_robustness encourage us to return zero
for reads.

Otherwise get_io_offset would return out-of-bound offset which may
result in out-of-bound loading/storing of inputs/outputs,
that could cause issues in drivers down the line.

Jason Ekstrand d86e38af2c nir: More NIR_MAX_VEC_COMPONENTS fixes 
A couple of these probably aren't strictly necessary but they won't
hurt.  The one that's particularly tricky is a fixed-length array in
nir_search.h.  However, to avoid blowing up the binary size of
nir_opt_algebraic by about 2x, we just assert that only small ops are
used.
