6f47bd9641 vk_memory_manager: Remove unified memory model flag
All drivers (even Intel) seem to have a device local memory type that is
not host visible. Remove this flag so all devices follow the same path.

This fixes a crash when trying to map to host device local memory on
integrated devices.

488ed8bd02 vk_rasterizer: Add lazy default buffer maker and use it for empty buffers
Introduce a default buffer getter that lazily constructs an empty
buffer. This is intended to match OpenGL's buffer 0.

Use this for disabled vertex and uniform buffers.

While we are at it, include vertex buffer usages for staging buffers to
silence validation errors.

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.

c81bf06d03 vulkan/wrapper: Sort physical devices
Sort discrete GPUs over the rest, Nvidia over AMD, AMD over Intel, Intel
over the rest. This gives us a somewhat consistent order when Optimus
is removed (renderdoc does this when it's attached).

This can break the configuration of users with an Intel GPU that
manually remove Optimus on yuzu. That said, it's a very unlikely to
happen.

d62f57cf5a fixed_pipeline_state: Hash and compare the whole structure
Pad FixedPipelineState's size to 384 bytes to be a multiple of 16.

Compare the whole struct with std::memcmp and hash with CityHash. Using
CityHash instead of a naive hash should reduce the number of collisions.
Improve used type traits to ensure this operation is safe.

With these changes the improvements to the hashable pipeline state are:

Optimized structure
Hash:            89 ns
Comparison:     103 ns
Construction*:  164 ns
Struct size:    384 bytes

Original structure
Hash:           148 ns
Equal:          174 ns
Construction*:  281 ns
Size:          1384 bytes

* Attribute state initialization is not measured

These measures are averages taken with std::chrono::high_accuracy_clock
on MSVC shipped on Visual Studio 16.6.0 Preview 2.1.

a7b6bd56d7 vk_stream_buffer: Fix out of memory on boot on recent Nvidia drivers
Nvidia recently introduced a new memory type for data streaming
(awesome!), but yuzu was assuming that all heaps had enough memory
for the assumed stream buffer size (256 MiB).

This worked fine on AMD but Nvidia's new memory heap was smaller than
256 MiB. This commit changes this assumption and allocates a bit less
than the size of the preferred heap, with a maximum of 256 MiB (to avoid
allocating all system memory on integrated devices).

- Fixes a crash on NVIDIA 450.82.0.0

090fd3fefa buffer_cache: Return handles instead of pointer to handles
The original idea of returning pointers is that handles can be moved.
The problem is that the implementation didn't take that in mind and made
everything harder to work with. This commit drops pointer to handles and
returns the handles themselves. While it is still true that handles can
be invalidated, this way we get an old handle instead of a dangling
pointer.

This problem can be solved in the future with sparse buffers.

e77337588e file_util: Early-exit in WriteArray and ReadArray if specified lengths are zero
It's undefined behavior to pass a null pointer to std::fread and
std::fwrite, even if the length passed in is zero, so we must perform
the precondition checking ourselves.

A common case where this can occur is when passing in the data of an
empty std::vector and size, as an empty vector will typically have a
null internal buffer.

While we're at it, we can move the implementation out of line and add
debug checks against passing in nullptr to std::fread and std::fwrite.

0e232cfdc1 renderer_vulkan: Integrate Nvidia Nsight Aftermath on Windows
Adds optional support for Nsight Aftermath. It is enabled through
ENABLE_NSIGHT_AFTERMATH in cmake. A path to the SDK has to be provided
by the environment variable NSIGHT_AFTERMATH_SDK.

Nsight Aftermath allows an application to generate "minidumps" of the
GPU state when a device loss happens. By analysing these on Nsight we
can know what a game was doing and why it triggered a device loss.

The dump is generated inside %APPDATA%\yuzu\log\gpucrash and this
directory is deleted every time a new instance is initialized with
Nsight enabled.

To enable it on yuzu there has a to be a driver and device capable of
running Nsight Aftermath on Vulkan. That means only Turing based GPUs
on the latest stable driver, beta drivers won't work for now.

It is manually enabled in Configuration>Debug>Enable Graphics Debugging
because when using all debugging capabilities there is a runtime cost.

76f178ba6e shader/video: Partially implement VMNMX
Implements the common usages for VMNMX. Inputs with a different size
than 32 bits are not supported and sign mismatches aren't supported
either.

VMNMX works as follows:
It grabs Ra and Rb and applies a maximum/minimum on them (this is
defined by .MX), having in mind the input sign. This result can then be
saturated. After the intermediate result is calculated, it applies
another operation on it using Rc. These operations are merges,
accumulations or another min/max pass.

This instruction allows to implement with a more flexible approach GCN's
min3 and max3 instructions (for instance).

94b0e2e5da texture_cache: Remove preserve_contents
preserve_contents was always true. We can't assume we don't have to
preserve clears because scissored and color masked clears exist.

This removes preserve_contents and assumes it as true at all times.

486a42c45a Buffer queue: Correct behavior of free buffer.
This corrects the behavior of free buffer after witnessing it in an
unrelated hardware test. I haven't found any games affected by it but in
name of better accuracy we'll correct such behavior.

a87b16da9a shader/texture: Remove type mismatches management from shader decoder
Since commit e22816a5bb we handle type mismatches from the CPU.
We don't need to hack our shader decoder due to game bugs anymore.

Removed in this commit.

common/file_util: Allow access to files on network shares
On Windows, network shares use paths like \\server\share\file which were
being broken by FileUtil::SanitizePath() removing double slashes.

Changed the code in SanitizePath to permit a double-backslash if it
occurs at the start of a filepath (on Windows only).

c6ea0d010b qt/bootmanager: Remove unnecessary glBindFramebuffer
Presentation context always has GL_DRAW_FRAMEBUFFER_BINDING as zero.
There is no need to bind the default framebuffer constantly.

According to Nsight this was using ~0.7ms per frame and it broke
renderdoc captures.

d7db088180 video_core/texture: Use a LUT to convert sRGB texture borders
This is a reversed look up table extracted from
https://gist.github.com/rygorous/2203834#file-gistfile1-cpp-L41-L62

that is used in
04d4e9e587/source/maxwell/tsc_generate.cpp (L38)

Games usually bind 0xFD expecting a float texture border of 1.0f.
The conversion previous to this commit was multiplying the uint8 sRGB
texture border color by 255. This is close to 1.0f but when that
difference matters, some graphical glitches appear.

This look up table is manually changed in the edges, clamping towards
0.0f and 1.0f.

While we are at it, move this logic to its own translation unit.
