Marek Olšák	b80bd58265	nir: skip nir_op_unpack_32_4x8 in nir_lower_alu_width ... The pass can't handle it just like the other unpack opcodes and generates invalid NIR.

Daniel Schürmann	be01e8711b	nir: introduce new nir_alu_alu_width() with nir_vectorize_cb callback ... This function allows to only scalarize instructions down to a desired vectorization width. nir_lower_alu_to_scalar() was changed to use the new function with a width of 1. Swizzles outside vectorization width are considered and reduce the target width. This prevents ending up with code like vec2 16 ssa_2 = iadd ssa_0.xz, ssa_1.xz which requires to emit shuffle code in backends and usually is not beneficial.
