* externals: Add oaksim submodule
Used for emitting ARM64 assembly
* common: Implement aarch64 ABI
Utilize oaknut to implement a stack frame.
* tests: Allow shader-jit tests for x64 and a64
Run the shader-jit tests for both x86_64 and arm64 targets
* video_core: Initialize arm64 shader-jit backend
Passes all current unit tests!
* shader_jit_a64: protect/unprotect memory when jit-ing
Required on MacOS. Memory needs to be fully unprotected and then
re-protected when writing or there will be memory access errors on
MacOS.
* shader_jit_a64: Fix ARM64-Imm overflow
These conditionals were throwing exceptions since the immediate values
were overflowing the available space in the `EOR` instructions. Instead
they are generated from `MOV` and then `EOR`-ed after.
* shader_jit_a64: Fix Geometry shader conditional
* shader_jit_a64: Replace `ADRL` with `MOVP2R`
Fixes some immediate-generation exceptions.
* common/aarch64: Fix CallFarFunction
* shader_jit_a64: Optimize `SantitizedMul`

* shader_jit_a64: Fix address register offset behavior
Based on https://github.com/citra-emu/citra/pull/6942
Passes unit tests.
* shader_jit_a64: Fix `RET` address offset
A64 stack is 16-byte aligned rather than 8. So a direct port of the x64
code won't work. Fixes weird branches into invalid memory for any
shaders with subroutines.
* shader_jit_a64: Increase max program size
Tuned for A64 program size.
* shader_jit_a64: Use `UBFX` for extracting loop-state

* shader_jit_a64: Optimize `SUB+CMP` to `SUBS`
Co-authored-by: JosJuice <JosJuice@users.noreply.github.com>
* shader_jit_a64: Optimize `CMP+B` to `CBNZ`

* shader_jit_a64: Use `FMOV` for `ONE` vector
Co-authored-by: JosJuice <JosJuice@users.noreply.github.com>
* shader_jit_a64: Remove x86-specific documentation
* shader_jit_a64: Use `UBFX` to extract exponent

* shader_jit_a64: Remove redundant MIN/MAX `SRC2`-NaN check
Special handling only needs to check SRC1 for NaN, not SRC2.
It would work as follows in the four possible cases:
No NaN: No special handling needed.
Only SRC1 is NaN: The special handling is triggered because SRC1 is NaN, and SRC2 is picked.
Only SRC2 is NaN: FMAX automatically picks SRC2 because it always picks the NaN if there is one.
Both SRC1 and SRC2 are NaN: The special handling is triggered because SRC1 is NaN, and SRC2 is picked.

* shader_jit/tests:: Add catch-stringifier for vec2f/vec3f
* shader_jit/tests: Add Dest Mask unit test
* shader_jit_a64: Fix Dest-Mask `BSL` operand order
Passes the dest-mask unit tests now.
* shader_jit_a64: Use `MOVI` for DestEnable mask
Accelerate certain cases of masking with MOVI as well
Co-authored-by: JosJuice <JosJuice@users.noreply.github.com>
* shader_jit/tests: Add source-swizzle unit test
This is not expansive. Generating all `4^4` cases seems to make Catch2
crash. So I've added some component-masking(non-reordering) tests based
on the Dest-Mask unit-test and some additional ones to test
broadcasts/splats and component re-ordering.
* shader_jit_a64: Fix swizzle index generation
This was still generating `SHUFPS` indices and not the ones that we wanted for the `TBL` instruction. Passes all unit tests now.
* shader_jit/tests: Add `ShaderSetup` constructor to `ShaderTest`
Rather than using the direct output of `CompileShaderSetup` allow a
`ShaderSetup` object to be passed in directly. This enabled the ability
emit assembly that is not directly supported by nihstro.
* shader_jit/tests: Add `CALL` unit-test
Tests nested `CALL` instructions to eventually reach an `EX2`
instruction.
EX2 is picked in particular since it is implemented as an even deeper
dispatch and ensures subroutines are properly implemented between `CALL`
instructions and implementation-calls.
* shader_jit_a64: Fix nested `BL` subroutines
`lr` was getting writen over by nested calls to `BL`, causing undefined
behavior with mixtures of `CALL`, `EX2`, and `LG2` instructions.
Each usage of `BL` is now protected with a stach push/pop to preserve
and restore teh `lr` register to allow nested subroutines to work
properly.
* shader_jit/tests: Allocate generated tests on heap
Each of these generated shader-test objects were causing the stack to
overflow. Allocate each of the generated tests on the heap and use
unique_ptr so they only exist within the life-time of the `REQUIRE`
statement.
* shader_jit_a64: Preserve `lr` register from external function calls
`EMIT` makes an external function call, and should be preserving `lr`
* shader_jit/tests: Add `MAD` unit-test
The Inline Asm version requires an upstream fix:
https://github.com/neobrain/nihstro/issues/68
Instead, the program code is manually configured and added.
* shader_jit/tests: Fix uninitialized instructions
These `union`-type instruction-types were uninitialized, causing tests
to indeterminantly fail at times.
* shader_jit_a64: Remove unneeded `MOV`
Residue from the direct-port of x64 code.
* shader_jit_a64: Use `std::array` for `instr_table`
Add some type-safety and const-correctness around this type as well.
* shader_jit_a64: Avoid c-style offset casting
Add some more const-correctness to this function as well.
* video_core: Add arch preprocessor comments
* common/aarch64: Use X16 as the veneer register
https://developer.arm.com/documentation/102374/0101/Procedure-Call-Standard
* shader_jit/tests: Add uniform reading unit-test
Particularly to ensure that addresses are being properly truncated
* common/aarch64: Use `X0` as `ABI_RETURN`
`X8` is used as the indirect return result value in the case that the
result is bigger than 128-bits. Principally `X0` is the general-case
return register though.
* common/aarch64: Add veneer register note
`LR` is generally overwritten by `BLR` anyways, and would also be a safe
veneer to utilize for far-calls.
* shader_jit_a64: Remove unneeded scratch register from `SanitizedMul`
* shader_jit_a64: Fix CALLU condition
Should be `EQ` not `NE`. Fixes the regression on Kid Icarus.
No known regressions anymore!

Adds the current viewport and scissor to the dynamic pipeline state to
reduce redundant viewport/scissor assignments in the command buffer.
This greatly reduces the amount of API calls to `vkCmdSetViewport` and
`vkCmdSetScissor` by only emitting the API call when the state actually
changes.
* vk_stream_buf: Avoid protected memory heaps
* Add an "Exclude" argument when finding a memory-type that avoids
`VK_MEMORY_PROPERTY_PROTECTED_BIT` by default
* vk_stream_buf: Utilize dedicated allocations when preferred by driver
`VK_KHR_dedicated_allocation` is part of the core Vulkan 1.1
specification and should be utilized when `prefersDedicatedAllocation`
is set.
* game_list: Treat demos as applications
Allows the dumping of RomFS from demos.
* game_list: Add TODO about using bitmasks for title ID high checks.

`DebugScope` was capturing a `string_view` in a lambda which is only
valid during the scope of this ctor. When the lambda gets invoked at a
later time, it will read undefined garbage. The lambda needs to make a
deep copy of this `string_view` into a `string` so that it is valid by
the time the scheduler invokes this lambda.
