ReinUsesLisp 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.

Lioncash c1c89411da video_core/control_flow: Provide operator!= for types with operator==
Provides operational symmetry for the respective structures.

Lioncash 1780e0e3d0 video_core/control_flow: Prevent sign conversion in TryGetBlock()
The return value is a u32, not an s32, so this would result in an
implicit signedness conversion.

Lioncash a162a844d2 video_core/control_flow: Remove unnecessary BlockStack copy constructor
This is the default behavior of the copy constructor, so it doesn't need
to be specified.

While we're at it we can make the other non-default constructor
explicit.

Lioncash 56bc11d952 video_core/control_flow: Use std::move where applicable

Lioncash e7b39f47f8 video_core/control_flow: Use the prefix variant of operator++ for iterators
Same thing, but potentially allows a standard library implementation to
pick a more efficient codepath.

Lioncash 47df844338 video_core/control_flow: Make program_size for ScanFlow() a std::size_t
Prevents a truncation warning from occurring with MSVC. Also the
internal data structures already treat it as a size_t, so this is just a
discrepancy in the interface.

Lioncash 3df9558593 video_core/control_flow: Place all internally linked types/functions within an anonymous namespace

Fernando Sahmkow 0b65e9335e Shader_Ir: Downgrade precision and rounding asserts to debug asserts.
This commit reduces the sevirity of asserts for FP precision and 
rounding as this are well known and have little to no consequences in 
gpu's accuracy.

Lioncash bebbdc2067 shader_ir: std::move Node instance where applicable
These are std::shared_ptr instances underneath the hood, which means
copying them isn't as cheap as a regular pointer. Particularly so on
weakly-ordered systems.

This avoids atomic reference count increments and decrements where they
aren't necessary for the core set of operations.

Lioncash 60926ac16b shader_ir: Rename Get/SetTemporal to Get/SetTemporary
This is more accurate in terms of describing what the functions are
actually doing. Temporal relates to time, not the setting of a temporary
itself.
