1a8424ceba nir: move tex_instr_remove_src
I want to re-use this in a different pass, so move to nir.h

Turns out it already exists.. so don't duplicate it.

d9156efc52 nir/lower_tex: Add support for lowering coordinate offsets
On i965, we can't support coordinate offsets for texelFetch or rectangle
textures.  Previously, we were doing this with a GLSL pass but we need to
do it in NIR if we want those workarounds for SPIR-V.

a41b57679f nir: Add a lowering pass for YUV textures
This lowers sampling from YUV textures to 1) one or more texture
instructions to sample each plane and 2) color space conversion to RGB.

fcd6b3f42b nir: coverity unitialized pointer read
Not sure how coverity arrives at the conclusion that we can read comp[j]
unitialized (around line 204), other than not being aware that ncomp is
greater than 1 so it won't underflow in the 'if (tex->is_array)' case.

5ec456375e nir: Separate texture from sampler in nir_tex_instr
This commit adds the capability to NIR to support separate textures and
samplers.  As it currently stands, glsl_to_nir only sets the texture deref
and leaves the sampler deref alone as it did before and nir_lower_samplers
assumes this.  Backends can still assume that they are combined and only
look at only at the texture index.  Or, if they wish, they can assume that
they are separate because nir_lower_samplers, tgsi_to_nir, and prog_to_nir
all set both texture and sampler index whenever a sampler is required (the
two indices are the same in this case).

ee85014b90 nir/tex_instr: Rename sampler to texture
We're about to separate the two concepts.  When we do, the sampler will
become optional.  Doing a rename first makes the separation a bit more
safe because drivers that depend on GLSL or TGSI behaviour will be fine to
just use the texture index all the time.
