This simplifies a bunch of places that no longer need special treatment
of value_count == 1. We rely on LLVM to optimize away the 1-element vector
types.
This fixes a bunch of bugs where 1-element arrays are indexed indirectly.

The scanning phase sets the driver_location, because it is part of the
ABI: radeonsi does the assignment differently.

The eventual goal is to hide all radv-specific details behind
ac_nir_context::abi, so that the NIR->LLVM code can be re-used by
radeonsi.
During development, we live with a partial split, where some of the
NIR->LLVM code still relies on linking back to the nir_to_llvm_context
(which should ultimately be renamed to reflect that it's radv-specific).
The idea is to get rid of these backlinks over time.

Translate the NIR variables directly to LLVM instead of lowering to a
TGSI-style giant array of vec4's and then back to a variable. This
should fix indirect dereferences, make shared variables more tightly
packed, and make LLVM's alias analysis more precise. This should fix an
upcoming Feral title, which has a compute shader that was failing to
compile because the extra padding made us run out of LDS space.
v2: Combine the previous two patches into one, only use this for shared
variables for now until LLVM becomes smarter.

The NIR parameters are ordered "compare, data", matching GLSL, but both
the image and buffer LLVM intrinsics take them the other way around.
This is already handled correctly for SSBO atomics.

NIR always makes the shift amount 32 bits, but LLVM asserts if the two
sources aren't the same type. Zero-extend the shift amount to make LLVM
happy.

We implement the split opcodes, and tell NIR to lower the original ones.
The lowering to LLVM is a little more complicated, but NIR can optimize
the split ones a little better, and some NIR lowering passes that we
might want to use (particularly for doubles) emit the split ones.
This should fix pack/unpackDouble2x32, which seems like a bug since when
we enabled the Float64 capability. It will also fix pack/unpackInt2x32
when we enable the Int64 capability.
Fixes: 798ae37c ("radv: Enable Float64 support.")
