NIR shifts are defined to truncate the shift amount to the number of bits
needed to represent the bit-size of the value shifted. LLVM treats large
shifts as poison. This fix achieves NIR semantics for shifts.
As an example, a|(b << 32), where "a" is 32bits, should produce a|b
according to NIR (because 32&31 == 0).
This caused LLVM to incorrectly optimize "(a >> c) | (b << (32 - c))" to a
u2u32(pack_64_2x32(a, b) >> c) (v_alignbit_b32), when the original NIR
should have returned "a | b" if c==0.

(cherry picked from commit 064336d359)
Found when 16bit vec3 varying with llvm14 (not found
when llvm15), one 32bit vec4 slot is filled like this:
vec3[0] | undef
vec3[1] | undef
vec3[2] | undef
undef | undef
LLVM error is for the elements with undef:
%287 = insertelement float %280, half %279, i64 0
After this change, we get:
%287 = insertelement <2 x half> %280, half %279, i64 0

Non-uniform descriptors are not loaded in NIR and instead the pointer is
passed to abi->load_sampler_desc. It can be the case that only the texture
or sampler uses this path.
For the descriptor which doesn't use the path, we would previously pass
NULL to abi->load_sampler_desc.

We actually don't need the type: lds is always treaded as
a "pointer to i8" in this function.
The caller will use the proper type when using the result.
For the same reason, we can get rid of the cast in setup_shared
because LLVM won't use this information anymore.
