maxwell_to_vk: Add uint16 vertex formats

gl_shader_cache: Use CompileDepth::FullDecompile on GLSL

gl_texture_cache: Fix layered texture attachment base level

shader/arithmetic: Add FCMP_CR variant

Revert "gl_shader_decompiler: Implement merges with bitfieldInsert"

vk_blit_screen: Initialize all members in VkPipelineViewportStateCreateInfo

Avoid invalid fallbacks.

When the dynamic state is specified, pViewports and pScissors are
ignored, quoting the specification:

  pViewports is a pointer to an array of VkViewport structures, defining
  the viewport transforms. If the viewport state is dynamic, this member
  is ignored.

That said, AMD's proprietary driver itself seem to read it regardless of
what the specification says.

vk_rasterizer: Default to 1 viewports with a size of 0

This is a simple optimization as Buffer Copies are mostly used for texture recycling. They are, however, useful when games abuse undefined behavior but most 3D APIs forbid it.

This reverts commit 05cf2708.

Apparently the first approach using floats instead of bitfieldInert
worked better for Fire Emblem: Three Houses. Reverting to get that
behavior back.

Adds another variant of FCMP.

service: friend: Stub IFriendService::GetBlockedUserListIds.

file_sys: patch_manager: Return early when there are no layers to apply.

- This is safe to stub, as there should be no adverse consequences from reporting no blocked users.

Silence validation layer errors.

From my testing on a Splatoon 2 shader that takes 3800ms on average to
compile changing to FullDecompile reduces it to 900ms on average.

The shader decoder will automatically fallback to a more naive method if
it can't use full decompile.

The base level is already included in the texture view. If we specify
the base level in the texture again, this will end up in the incorrect
level and potentially out of bounds.

renderer_vulkan: Drop Vulkan-Hpp

gl_rasterizer: Implement line widths and smooth lines

texture_cache: Remove preserve_contents

texture/astc: More small ASTC optimizations

shader/conversion: Implement I2I sign extension, saturation and selection

gl_texture_cache: Attach view instead of base texture for layered attchments

gl_shader_decompiler: Improve generated code in HMergeH*

shader/texture: Remove type mismatches management from shader decoder

Implements "legacy" features from OpenGL present on hardware such as
smooth lines and line width.

This also fixes Turing issues but it avoids doing more bitcasts. This
should improve the generated code while also avoiding more points where
compilers can flush floats.

service/vi: Partially implement BufferQueue disconnect

shader/video: Partially implement VMNMX

video_core: Add MSAA registers in 3D engine and TIC

Avoiding bitwise expressions, this fixes Turing issues in shaders using
half float merges that affected several games.

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).

This adds the registers used for multisampling. It doesn't implement
anything for now.

Buffer queue: Correct behavior of free buffer.

Port citra-emu/citra#4956: "Fixes to game list sorting"

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.
