82ae8b1d33 treewide: simplify nir_def_rewrite_uses_after
Most of the time with nir_def_rewrite_uses_after, you want to rewrite after the
replacement. Make that the default thing to be more ergonomic and to drop
parent_instr uses.

We leave nir_def_rewrite_uses_after_instr defined if you really want the old
signature with an arbitrary after point.

Via Coccinelle patch:

    @@
    expression a, b;
    @@

    -nir_def_rewrite_uses_after(a, b, b->parent_instr)
    +nir_def_rewrite_uses_after_def(a, b)

Followed by a bunch of sed.

This converts a lot of trivial passes. Nice boilerplate deletion. Via Coccinelle
patch (with a small manual fix-up for panfrost where coccinelle got confused by
genxml + ninja clang-format squashed in, and for Zink because my semantic patch
was slightly buggy).

4695bebc79 nir: Drop nir_dest
Instead, we replace every use of it with nir_def.  Most of this commit
was generated by sed:

   sed -i -e 's/dest.ssa/def/g' src/**/*.h src/**/*.c src/**/*.cpp

A few manual fixups were required in lima and the nir_legacy code.

4bb6e6817e intel: Use a system value for gl_FragCoord
It's kind-of an anomaly that the Intel drivers are still treating
gl_FragCoord as an input.  It also makes zero sense because we have to
special-case it in the back-end.

Because ANV is the only user of nir_lower_wpos_center, we go ahead and
just update it to look for nir_intrinsic_load_frag_coord as part of this
patch.

cf7fb39805 nir/lower_wpos_center: Look at derefs for modes
This is instead of looking all the way back to the variable which may
not exist for all derefs.  This makes this code properly ignore casts
with modes other than the mode[s] we care about (where casts aren't
allowed).

d80c342d89 nir: add deref lowering sanity checking
This will be removed at the end of the transition, but add some tracking
plus asserts to help ensure that lowering passes are called at the
correct point (pre or post deref instruction lowering) as passes are
converted and the point where lower_deref_instrs() is called is moved.

023ea3772d nir/lower_wpos_center: support adding sample position to fragment coordinate
According to section 14.6 of the Vulkan specification:

   "When sample shading is enabled, the x and y components of FragCoord
    reflect the location of the sample corresponding to the shader
    invocation."

So add a boolean parameter to the lowering pass to select this behavior
when we need it.

6e5d86c07a nir: Add a simple nir_lower_wpos_center() pass for Vulkan drivers.
nir_lower_wpos_ytransform() is great for OpenGL, which allows
applications to choose whether their coordinate system's origin is
upper left/lower left, and whether the pixel center should be on
integer/half-integer boundaries.

Vulkan, however, has much simpler requirements: the pixel center
is always half-integer, and the origin is always upper left.  No
coordinate transform is needed - we just need to add <0.5, 0.5>.
This means that we can avoid using (and setting up) a uniform.

I thought about adding more options to nir_lower_wpos_ytransform(),
but making a new pass that never even touched uniforms seemed simpler.

v2: Use normal iterator rather than _safe variant (noticed by Matt).
