ReinUsesLisp e2b67a868b shader/other: Implement thread comparisons (NV_shader_thread_group)
Hardware S2R special registers match gl_Thread*MaskNV. We can trivially
implement these using Nvidia's extension on OpenGL or naively stubbing
them with the ARB instructions to match. This might cause issues if the
host device warp size doesn't match Nvidia's. That said, this is
unlikely on proper shaders.

Refer to the attached url for more documentation about these flags.

ReinUsesLisp 891236124c buffer_cache: Use boost::intrusive::set for caching
Instead of using boost::icl::interval_map for caching, use
boost::intrusive::set. interval_map is intended as a container where the
keys can overlap with one another; we don't need this for caching
buffers and a std::set-like data structure that allows us to search with
lower_bound is enough.

ReinUsesLisp 420cc13248 renderer_opengl: Add assembly program code paths
Add code required to use OpenGL assembly programs based on
NV_gpu_program5. Decompilation for ARB programs is intended to be added
in a follow up commit. This does **not** include ARB decompilation and
it's not in an usable state.

The intention behind assembly programs is to reduce shader stutter
significantly on drivers supporting NV_gpu_program5 (and other required
extensions). Currently only Nvidia's proprietary driver supports these
extensions.

Add a UI option hidden for now to avoid people enabling this option
accidentally.

This code path has some limitations that OpenGL compatibility doesn't
have:
- NV_shader_storage_buffer_object is limited to 16 entries for a single
OpenGL context state (I don't know if this is an intended limitation, an
specification issue or I am missing something). Currently causes issues
on The Legend of Zelda: Link's Awakening.
- NV_parameter_buffer_object can't bind buffers using an offset
different to zero. The used workaround is to copy to a temporary buffer
(this doesn't happen often so it's not an issue).

On the other hand, it has the following advantages:
- Shaders build a lot faster.
- We have control over how floating point rounding is done over
individual instructions (SPIR-V on Vulkan can't do this).
- Operations on shared memory can be unsigned and signed.
- Transform feedbacks are dynamic state (not yet implemented).
- Parameter buffers (uniform buffers) are per stage, matching NVN and
hardware's behavior.
- The API to bind and create assembly programs makes sense, unlike
ARB_separate_shader_objects.

ReinUsesLisp 8b329ddcc9 gl_shader_decompiler: Properly emulate NaN behaviour on NE
"Not equal" operators on GLSL seem to behave as unordered when we expect
an ordered comparison.

Manually emulate this checking for LGE values (numbers, not-NaNs).

ReinUsesLisp fe931ac976 {maxwell_3d,buffer_cache}: Implement memory barriers using 3D registers
Drop MemoryBarrier from the buffer cache and use Maxwell3D's register
WaitForIdle.

To implement this on OpenGL we just call glMemoryBarrier with the
necessary bits.

Vulkan lacks this synchronization primitive, so we set an event and
immediately wait for it. This is not a pretty solution, but it's what
Vulkan can do without submitting the current command buffer to the queue
(which ends up being more expensive on the CPU).

ReinUsesLisp bb1ed66d99 maxwell_3d: Fix depth clamping register
Using deko3d as reference:
4e47ba0013/source/maxwell/gpu_3d_state.cpp (L42)

We were using bits 3 and 4 to determine depth clamping, but these are
the same both enabled and disabled:

state->depthClampEnable ? 0x101A : 0x181D

The same happens on Nvidia's OpenGL driver, where they do something like
this (default capabilities, GL 4.5 compatibility):

(state & DEPTH_CLAMP) != 0 ? 0x201a : 0x281c

There's always a difference between the first bits in this register, but
bit 11 is consistently disabled on both deko3d/NVN and OpenGL. This
commit changes yuzu's behaviour to use bit 11 to determine depth
clamping.

- Fixes depth issues on Super Mario Odyssey's intro.

ReinUsesLisp 8da16cf9fb texture_cache: Reintroduce preserve_contents accurately
This reverts commit 94b0e2e5da.

preserve_contents proved to be a meaningful optimization. This commit
reintroduces it but properly implemented on OpenGL.

We have to make sure the clear removes all the previous contents of the
image.

It's not currently implemented on Vulkan because we can do smart things
there that's preferred to be introduced in a separate commit.

ReinUsesLisp 0bbae63300 gl_rasterizer: Fix buffers without size
On NVN buffers can be enabled but have no size. According to deko3d and
the behavior we see in Animal Crossing: New Horizons these buffers get
the special address of 0x1000 and limit themselves to 0xfff.

Implement buffers without a size by binding a null buffer to OpenGL
without a side.
