gl_shader_decompiler: Avoid copies where applicable

Fix process memory initialization for ELF and NRO

fixed_pipeline_state: Pack structure, use memcmp and CityHash on it

General: Resolve minor assorted warnings

core: arm_unicorn: Fix interpret fallback by temporarily mapping instruction page.

* audio_renderer: Preliminary BehaviorInfo

* clang format

* Fixed IsRevisionSupported

* fixed IsValidRevision

* Fixed logic error & spelling errors & crash

* Addressed issues

maxwell_3d: Initialize format attributes constant as one

Initialize quad_indexed_pass before uint8_pass

- We need this for homebrew process initialization.

dynarmic: Add option to disable CPU JIT optimizations

Try to reduce log spam a bit by lowering log levels to Debug

vk_stream_buffer: Fix out of memory on boot on recent Nvidia drivers

service: Remove unused RequestParser instances

am: Resolve ineffective moves

Fixes Werror=reorder in gcc

dma_pusher: Remove reliance on the global system instance

vk_compute_pass: Implement indexed quads

With this, the video core is now has no calls to the global system
instance at all.

texture_cache/format_lookup_table: Fix incorrect green, blue, and alpha indices

hle_ipc: Remove std::size_t casts where applicable

yuzu/main: Add better popup texts and remove duplicated actions

track: Eliminate redundant copies

Unbreak Vulkan on FreeBSD

Unbreak -Werror=implicit-fallthrough with Clang

Pad FixedPipelineState's size to 384 bytes to be a multiple of 16.

Compare the whole struct with std::memcmp and hash with CityHash. Using
CityHash instead of a naive hash should reduce the number of collisions.
Improve used type traits to ensure this operation is safe.

With these changes the improvements to the hashable pipeline state are:

Optimized structure
Hash:            89 ns
Comparison:     103 ns
Construction*:  164 ns
Struct size:    384 bytes

Original structure
Hash:           148 ns
Equal:          174 ns
Construction*:  281 ns
Size:          1384 bytes

* Attribute state initialization is not measured

These measures are averages taken with std::chrono::high_accuracy_clock
on MSVC shipped on Visual Studio 16.6.0 Preview 2.1.
