ReinUsesLisp 2a96bea6a7 shader/arithmetic_integer: Change IAdd to UAdd to avoid signed overflow
Signed integer addition overflow might be undefined behavior. It's free
to change operations to UAdd and use unsigned integers to avoid
potential bugs.

ReinUsesLisp c788f9c0bd shader/arithmetic_integer: Implement IADD.X
IADD.X takes the carry flag and adds it to the result. This is generally
used to emulate 64-bit operations with 32-bit registers.

ReinUsesLisp ffc5ec6fa8 decode/register_set_predicate: Implement CC
P2R CC takes the state of condition codes and puts them into a register.
We already have this implemented for PR (predicates). This commit
implements CC over that.

ReinUsesLisp dbaebd8582 decode/arithmetic_half: Fix HADD2 and HMUL2 absolute and negation bits
The encoding for negation and absolute value was wrong.
Extracting is now done manually. Similar instructions having different
encodings is the rule, not the exception. To keep sanity and readability
I preferred to extract the desired bit manually.

This is implemented against nxas:
8dbc389957/table.h (L68)

That is itself tested against nvdisasm (Nvidia's official disassembler).

ReinUsesLisp 4fb921ff6b shader/texture: Support multiple unknown sampler properties
This allows deducing some properties from the texture instruction before
asking the runtime. By doing this we can handle type mismatches in some
instructions from the renderer instead of the shader decoder.

Fixes texelFetch issues with games using 2D texture instructions on a 1D
sampler.

Lioncash d159643fd7 decode/texture: Resolve unused variable warnings.
Some variables aren't used, so we can remove these.

Unfortunately, diagnostics are still reported on structured bindings
even when annotated with [[maybe_unused]], so we need to unpack the
elements that we want to use manually.

Lioncash 1c340c6efa CMakeLists: Specify -Wextra on linux builds
Allows reporting more cases where logic errors may exist, such as
implicit fallthrough cases, etc.

We currently ignore unused parameters, since we currently have many
cases where this is intentional (virtual interfaces).

While we're at it, we can also tidy up any existing code that causes
warnings. This also uncovered a few bugs as well.

ReinUsesLisp 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).

ReinUsesLisp 2339fe199f shader_decompiler: Remove FragCoord.w hack and change IPA implementation
Credits go to gdkchan and Ryujinx. The pull request used for this can
be found here: https://github.com/Ryujinx/Ryujinx/pull/1082

yuzu was already using the header for interpolation, but it was missing
the FragCoord.w multiplication described in the linked pull request.
This commit finally removes the FragCoord.w == 1.0f hack from the shader
decompiler.

While we are at it, this commit renames some enumerations to match
Nvidia's documentation (linked below) and fixes component declaration
order in the shader program header (z and w were swapped).

ReinUsesLisp 46791c464a shader/conversion: Fix F2F rounding operations with different sizes
Rounding operations only matter when the conversion size of source and
destination is the same, i.e. .F16.F16, .F32.F32 and .F64.F64.

When there is a mismatch (.F16.F32), these bits are used for IEEE
rounding, we don't emulate this because GLSL and SPIR-V don't support
configuring it per operation.
