manually check for NAN.

3185245845 shader/memory: Implement RED.E.ADD
Implements a reduction operation. It's an atomic operation that doesn't
return a value.

This commit introduces another primitive because some shading languages
might have a primitive for reduction operations.

d95d4ac843 shader/memory: Implement ATOM.ADD
ATOM operates atomically on global memory. For now only add ATOM.ADD
since that's what was found in commercial games.

This asserts for ATOM.ADD.S32 (handling the others as unimplemented),
although ATOM.ADD.U32 shouldn't be any different.

This change forces us to change the default type on SPIR-V storage
buffers from float to uint. We could also alias the buffers, but it's
simpler for now to just use uint. While we are at it, abstract the code
to avoid repetition.

b3371ed09e Shader_IR: add the ability to amend code in the shader ir.
This commit introduces a mechanism by which shader IR code can be
amended and extended. This useful for track algorithms where certain
information can derived from before the track such as indexes to array
samplers.

shader/node: Unpack bindless texture encoding
Bindless textures were using u64 to pack the buffer and offset from
where they come from. Drop this in favor of separated entries in the
struct.

Remove the usage of std::set in favor of std::list (it's not std::vector
to avoid reference invalidations) for samplers and images.

4e35177e23 shader_ir: Implement VOTE
Implement VOTE using Nvidia's intrinsics. Documentation about these can
be found here
https://developer.nvidia.com/reading-between-threads-shader-intrinsics

Instead of using portable ARB instructions I opted to use Nvidia
intrinsics because these are the closest we have to how Tegra X1
hardware renders.

To stub VOTE on non-Nvidia drivers (including nouveau) this commit
simulates a GPU with a warp size of one, returning what is meaningful
for the instruction being emulated:

* anyThreadNV(value) -> value
* allThreadsNV(value) -> value
* allThreadsEqualNV(value) -> true

ballotARB, also known as "uint64_t(activeThreadsNV())", emits

VOTE.ANY Rd, PT, PT;

on nouveau's compiler. This doesn't match exactly to Nvidia's code

VOTE.ALL Rd, PT, PT;

Which is emulated with activeThreadsNV() by this commit. In theory this
shouldn't really matter since .ANY, .ALL and .EQ affect the predicates
(set to PT on those cases) and not the registers.
