This makes texture instructions a lot less annoying to construct, especially in
cases where the deref-based helpers don't work.
I only converted core NIR, not the drivers. Since it was by hand.

This simplifies things a bit. Note that in some cases, the arguments are
swapped, because multiplications are commutative, and nir_fmul_imm only
allows the second operand to be an immediate.

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

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.

This is almost always a nir_instr and updating the src of a nir_if will
have to work slightly differently in the future.

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.

All of these are pretty well-defined. Rather than implementing them
as a sequence of nir ops, we can just use the libclc implementation.

Moves build_atan and build_atan2 into nir_builtin_builder. The goal is
to be able to use this from the GLSL translator too.

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.

not getting far enough yet to hit most of the OpenCL.std instructions.
Anyway, this is better than nothing and covers the most common builtins.
