Shadow sampler 2D arrays are supported on OpenGL, so there's no reason
to forbid these. Enable textureLod usage on these.

ReinUsesLisp 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.

shader/memory: Implement LDG.U8 and unaligned U8 loads 
LDG can load single bytes instead of full integers or packs of integers.
These have the advantage of loading bytes that are not aligned to 4
bytes.

To emulate these this commit gets the byte being referenced (by doing
"address & 3" and then using that to extract the byte from the loaded
integer:

result = bitfieldExtract(loaded_integer, (address % 4) * 8, 8)

shader/conversion: Implement byte selector in I2F 
I2F's byte selector is used to choose what bytes to convert to float.
e.g. if the input is 0xaabbccdd and the selector is ".B3" it will
convert 0xaa. The default (when it's not shown in nvdisasm) is ".B0", in
that example the default would convert 0xdd to float.

shader/texture: Handle TLDS texture type mismatches 
Some games like "Fire Emblem: Three Houses" bind 2D textures to offsets
used by instructions of 1D textures. To handle the discrepancy this
commit uses the the texture type from the binding and modifies the
emitted code IR to build a valid backend expression.

E.g.: Bound texture is 2D and instruction is 1D, the emitted IR samples
a 2D texture in the coordinate ivec2(X, 0).

These warnings don't offer meaningful information while decoding
shaders. Remove them.

Fernando Sahmkow 23cabc98db Shader_IR: Fix regression on TLD4 
Originally on the last commit I thought TLD4 acted the same as TLD4S and 
didn't have a mask. It actually does have a component mask. This commit 
corrects that.

Fernando Sahmkow 9293c3a0f2 Shader_IR: Fix TLD4 and add Bindless Variant. 
This commit fixes an issue where not all 4 results of tld4 were being
written, the color component was defaulted to red, among other things.
It also implements the bindless variant.

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.

Lioncash 382717172e shader_ir: Use std::array with pair instead of unordered_map 
Given the overall size of the maps are very small, we can use arrays of
pairs here instead of always heap allocating a new map every time the
functions are called. Given the small size of the maps, the difference
in container lookups are negligible, especially given the entries are
already sorted.

ReinUsesLisp 1ea07954fb shader_ir/memory: Ignore global memory when tracking fails 
Ignore global memory operations instead of invoking undefined behaviour
when constant buffer tracking fails and we are blasting through asserts,
ignore the operation.

In the case of LDG this means filling the destination registers with
zeroes; for STG this means ignore the instruction as a whole.

The default behaviour is still to abort execution on failure.

Lioncash a2eccbf075 video_core/shader/ast: Make Indent() return a string_view 
The returned string is simply a substring of our constexpr tabs

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.
