maxwell_3d: Make dirty_pointers private

renderer_opengl/utils: Forward declare private structs 

Fix git version in scm_rev.cpp

This isn't used outside of the class itself, so we can make it private
for the time being.

Nothing from these headers are used, so they can be removed.

Keeps the definitions hidden and allows changes to the structs without
needing to recompile all users of classes containing said structs.

control_flow: Silence -Wreorder warning for CFGRebuildState

gl_shader_cache: Remove unused variables

Organizes the initializer list in the same order that the variables
would actually be initialized in.

GUI/configure: resize hotkeys action column to fit content

Given this isn't used, this can be removed entirely.

Avoids several reallocations of std::vector instances where applicable.

Eliminates a few unnecessary constructions of std::vectors.

shader_ir/memory: Implement u16 and u8 for STG and LDG

shader_ir/texture: Simplify AOFFI code

maxwell_to_vk: Implement GL_CLAMP hacking Nvidia's driver

core/kernel: Fix GetTotalPhysicalMemoryUsed.

vk_compute_pass: Add compute passes to emulate missing Vulkan features

module._memory was already moved over to a new shared_ptr.
So code_memory_size was not increased at all.

This lowers the heap space and so saves a bit of memory, usually between 50 to 100 MB.

This fixes a regression of c0a01f3a

Comment hardcoded SPIR-V modules.

Nvidia's driver defaults invalid enumerations to GL_CLAMP. Vulkan
doesn't expose GL_CLAMP through its API, but we can hack it on Nvidia's
driver using the internal driver defaults.

Using the same technique we used for u8 on LDG, implement u16.

In the case of STG, load memory and insert the value we want to set
into it with bitfieldInsert. Then set that value.

This currently only supports quad arrays and u8 indices.

In the future we can remove quad arrays with a table written from the
CPU, but this was used to bootstrap the other passes helpers and it
was left in the code.

The blob code is generated from the "shaders/" directory. Read the
instructions there to know how to generate the SPIR-V.

vk_pipeline_cache: Initial implementation

service: vi: Implement CloseLayer.

Given a pipeline key, this cache returns a pipeline abstraction (for
graphics or compute).

This abstractio represents the state of the 3D engine at a given draw.
Instead of changing individual bits of the pipeline how it's done in
APIs like D3D11, OpenGL and NVN; on Vulkan we are forced to put
everything together into a single, immutable object.

It takes advantage of the few dynamic states Vulkan offers.

This abstraction represents a Vulkan compute pipeline.

This function allows us to share code between compute and graphics
pipelines compilation.

vk_update_descriptor/vk_renderpass_cache: Add pipeline cache dependencies

renderer_vulkan: Buffer cache, stream buffer and memory manager changes

The renderpass cache is used to avoid creating renderpasses on each
draw. The hashed structure is not currently optimized.

The update descriptor is used to store in flat memory a large chunk of
staging data used to update descriptor sets through templates. It
provides a push interface to easily insert descriptors following the
current pipeline. The order used in the descriptor update template has
to be implicitly followed. We can catch bugs here using validation
layers.

The stream buffer before this commit once it was full (no more bytes to
write before looping) waiting for all previous operations to finish.
This was a temporary solution and had a noticeable performance penalty
in performance (from what a profiler showed).

To avoid this mark with fences usages of the stream buffer and once it
loops wait for them to be signaled. On average this will never wait.
Each fence knows where its usage finishes, resulting in a non-paged
stream buffer.

On the other side, the buffer cache is reimplemented using the generic
buffer cache. It makes use of the staging buffer pool and the new
stream buffer.
