This reverts #4713. The implementation in that PR is not accurate.
It does not reflect the behavior seen in hardware.

shader_ir: std::move node within DeclareAmend()
|
|
Same behavior, but elides an unnecessary atomic reference count
increment and decrement.
|
|
fmt now automatically prints the numeric value of an enum class member
by default, so we don't need to use casts any more.
Reduces the line noise a bit.

Cleans out the rest of the occurrences of variable shadowing and makes
any further occurrences of shadowing compiler errors.

Removes const from some variables that are returned from functions, as
this allows the move assignment/constructors to execute for them.
|
|
This allows us to use native SPIR-V instructions without having to
manually check for NAN.
|
|
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.

This commit introduces a mechanism by which shader IR code can be
amended and extended. This useful for track algorithms where certain
information can derived from before the track such as indexes to array
samplers.

Given the overall size of the maps are very small, we can use arrays of
pairs here instead of always heap allocating a new map every time the
functions are called. Given the small size of the maps, the difference
in container lookups are negligible, especially given the entries are
already sorted.

This instruction writes to a memory buffer shared with threads within
the same work group. It is known as "shared" memory in GLSL.

These are std::shared_ptr instances underneath the hood, which means
copying them isn't as cheap as a regular pointer. Particularly so on
weakly-ordered systems.
This avoids atomic reference count increments and decrements where they
aren't necessary for the core set of operations.

This is more accurate in terms of describing what the functions are
actually doing. Temporal relates to time, not the setting of a temporary
itself.

shader/track: Track indirect buffers

gl_shader_decompiler: Implement gl_ViewportIndex and gl_Layer in vertex shaders
|
|
While changing this code, simplify tracking code to allow returning
the base address node, this way callers don't have to manually rebuild
it on each invocation.

This commit implements gl_ViewportIndex and gl_Layer in vertex and
geometry shaders. In the case it's used in a vertex shader, it requires
ARB_shader_viewport_layer_array. This extension is available on AMD and
Nvidia devices (mesa and proprietary drivers), but not available on
Intel on any platform. At the moment of writing this description I don't
know if this is a hardware limitation or a driver limitation.
In the case that ARB_shader_viewport_layer_array is not available,
writes to these registers on a vertex shader are ignored, with the
appropriate logging.

Instead of having a vector of unique_ptr stored in a vector and
returning star pointers to this, use shared_ptr. While changing
initialization code, move it to a separate file when possible.
This is a first step to allow code analysis and node generation beyond
the ShaderIR class.

This allows for forming comment nodes without making unnecessary copies
of the std::string instance.
e.g. previously:
Comment(fmt::format("Base address is c[0x{:x}][0x{:x}]",
cbuf->GetIndex(), cbuf_offset));
Would result in a copy of the string being created, as CommentNode()
takes a std::string by value (a const ref passed to a value parameter
results in a copy).
Now, only one instance of the string is ever moved around. (fmt::format
returns a std::string, and since it's returned from a function by value,
this is a prvalue (which can be treated like an rvalue), so it's moved
into Comment's string parameter), we then move it into the CommentNode
constructor, which then moves the string into its member variable).

Given the class contains quite a lot of non-trivial types, place the
constructor and destructor within the cpp file to avoid inlining
construction and destruction code everywhere the class is used.
