01e9ee79f7 nir: Drop unused name from nir_ssa_dest_init
Since 624e799cc3 ("nir: Drop nir_ssa_def::name and nir_register::name"), SSA
defs don't have names, making the name argument unused. Drop it from the
signature and fix the call sites. This was done with the help of the following
Coccinelle semantic patch:

    @@
    expression A, B, C, D, E;
    @@

    -nir_ssa_dest_init(A, B, C, D, E);
    +nir_ssa_dest_init(A, B, C, D);

e67e2293fa nir/builder: Rework the boolean conversion helpers
Move them up to where the other conversion helpers.  For nir_b2<T>(),
suffix them with N like all the others and make them use
nir_type_convert() as well.

69ba1c4d59 nir: adjust nir_src_copy signature to take a nir_instr *
This is almost always a nir_instr and updating the src of a nir_if will
have to work slightly differently in the future.

1cb3d1a6ae nir: Produce correct results for atan with NaN
Properly handling NaN adversely affects several hundred shaders in
shader-db (lots of Skia and a few others from various synthetic
benchmarks) and fossil-db (mostly Talos and some Doom 2016).  Only apply
the NaN handling work-around when the shader demands it.

v2: Add comment explaining the 1.0*y_over_x.  Suggested by Caio.

ddd08e1888 nir/builder: Remove the use_fmov parameter from nir_swizzle
This flag has caused more confusion than good in most cases.  You can
validly use imov for floats or fmov for integers because, without source
modifiers, neither modify their input in any way.  Using imov for floats
is more reliable so we go that direction.
