This also adds some basic memory usage accounting. These two types are
used by Super Smash Bros. during startup.

This adds some structures necessary to support multiple memory regions
in the future. It also adds support for different system memory types
and the new linear heap mapping at 0x30000000.

These helpers aren't really part of the kernel, and mem_map.cpp/h is
going to be moved there next.

Handle invalid `Log::Class`

Vertex Shader JIT for X86-64

- Config: Add an option for selecting to use shader JIT or interpreter.
- Qt: Add a menu option for enabling/disabling the shader JIT.

- Also renames "vertex_shader.*" to "shader_interpreter.*"

Add a case of `Log::Class::Count` to the switch statement that
dispatches on `Log::Class`.  The case simply calls the `UNREACHABLE`
macro.

debugger: Add the ability to view VFP register contents

Stop defining GCC always_inline attributes as __forceinline

__forceinline is a MSVC extension, which may confuse some people working on the codebase.
Furthermore, the C++ standard dictates that all names which contain adjacent underscores are reserved.

Replace standard uint*_t and int*_t with CommonTypes’ u* and s* types

ARM Core, Video Core, CitraQt, Citrace: Use CommonTypes types instead of the standard u?int*_t types.
