This isn't necessary in a cpp file and will cause warnings on clang.

Prevents header churn and needing to recompile these files if these
headers are ever changed in the future.

Prevents unused variable warnings.

This allows tuning standard library implementations to enable or disable
range checks at runtime, which is nicer for debugging.

Prevents variable name clashing.

Resolves a -Wextra-semi warning.

While we're at it, we can invert the branch to form a guard clause,
unindenting all of the contained code.

IoctlGetGpuTime should be 16 bytes, not 8.

Closes #3533

Turns out the functions were already implemented but just never added

Closes #3026

SetShimLibraryVersion, SaveScreenShotEx1 & SaveScreenShotEx2 were missing

Closes #3829

No point to emulate battery life. However options are broken out if we ever want to add a setting for it

Properly implement IApplicationFunctions::GetDisplayVersion

Return the proper state of vr mode for IsVrModeEnabled
We should not return an error for SetVrModeEnabled. When VR Mode is turned on, it signals to lbl to turn vr mode on, not return an error code

We're not suppose to pop a u64, should just read the sent pid and check that

Reduces some header churn and reduces rebuilds when some header
internals change.

While we're at it we can also resolve a missing include in buffer_cache.

This temporary is not needed as we mark Rd.CC + IADD.X as unimplemented.
It caused issues when tracking global buffers.

As we currently match hardware and don't return a successful result, these should be marked as errors instead of warnings and as stubs.

Consistency for the rest of the error codes in the codebase

Closes #2874

Xenoblade 2 invokes a draw call with zero vertices.
This is likely due to indirect drawing (glDrawArraysIndirect).

This causes a crash in the staging buffer pool when trying to create a
buffer with a size of zero. To workaround this, skip index buffer setup
entirely when the number of indices is zero.

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).

Using deko3d as reference:
https://github.com/devkitPro/deko3d/blob/4e47ba0013552e592a86ab7a2510d1e7dadf236a/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.

This reverts commit 94b0e2e5.

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.

Deduplicate code shared between vk_pipeline_cache and gl_shader_cache as
well as shader decoder code.

While we are at it, fix a bug in gl_shader_cache where compute shaders
had an start offset of a stage shader.

IADD.X Rd.CC requires some extra logic that is not currently
implemented. Abort when this is hit.

Signed integer addition overflow might be undefined behavior. It's free
to change operations to UAdd and use unsigned integers to avoid
potential bugs.

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.

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.
