ctz is a CL2.0 opcode but 3.0 requires it as well so just add support
for it.
Tested against CTS integer_ops integer_ctz test.

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

It was always fneu but naming it fne causes confusion from time to time. So
lets rename it. Later we also want to add other unordered and fne, this is
a smaller preparation for that.

Because it's in double-quotes, it will search the current folder before
any search paths. Since nir_builder.h and nir_builtin_builder.h are in
the same folder, this guarantees a correct include. However,
nir/nir_builder.h does not unless the includer's path is set up just
right.

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

Not complete, mostly just adding things as I encounter them in CTS. But
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.
