This pass doesn't handle deref instructions yet.  Making it handle both
legacy derefs and deref instructions would be painful.  Since it's not
important for correctness, just disable it for now.

Sometimes it's useful for a pass to be able to clean up its own derefs
instead of waiting for DCE.  This little helper makes it very easy.

This commit introduces a new nir_deref.h header for helpers that are
less common and really only needed by a few heavy-duty passes.  In this
header is a new struct for representing a full deref path which can be
walked in either direction.

This will be needed by anything which changes variable modes without
rewriting derefs.

This replaces some "if (...} { }" with "if (...) continue;" to reduce
nesting depth and makes nir_metadata_preserve conditional on progress
for the given impl.

Non-intrinsic function handling has never actually been tested and
probably doesn't work.  Just get rid of it for now.  We can always add
it back in later if it's useful.

This inserts a call to nir_lower_deref_instrs at every call site of
glsl_to_nir, spirv_to_nir, and prog_to_nir.

This commit adds a pass for lowering deref instructions to deref chains
as well as some smaller helpers to ease the transition.

This commit adds a new instruction type to NIR for handling derefs.
Nothing uses it yet but this adds the data structure as well as all of
the code to validate, print, clone, and [de]serialize them.

Generated with

git grep -l nir_intrinsic_image | xargs \
sed -i 's/nir_intrinsic_image/nir_intrinsic_image_var/g'

and some manual fixing in nir_intrinsics.h

We were validating this for locals but nothing else.

This fixes the fs-interpolateAtCentroid-block-array piglit test on i965.

Because nir_instr_remove is an inline wrapper around nir_instr_remove_v,
the compiler should be able to tell that the return value is unused and
not emit the extra code in most cases.

We already have these for bit_size

We're already including it in the meson build.  This fixes build issues
on systems which have a drm_fourcc.h that doesn't have modifiers.
