Shader instructions MOV_C, MOV_R, and several minor GPU things

file_util: Minor changes to IOFile

Without this, it's possible to get compilation failures in the (rare) scenario where
a container is used to store a bunch of live IOFile instances, as they may be using
std::move_if_noexcept under the hood. Given these definitely don't throw exceptions
this is also not incorrect to add either.

Ensure that the actual types being passed in are trivially copyable. The internal
call to ReadArray() and WriteArray() will always succeed, since they're passed a pointer to char*
which is always trivially copyable.

Shaders: Implemented predicate condition 3 (LessEqual) in the fset and fsetp instructions.

gl_shader_decompiler: Implement MOV32I, partially implement I2I, I2F

set/am: Fix code for getting language codes

fermi_2d: Fix surface copy block height.

file_util: Remove compiler version checks around is_trivially_copyable

externals: Update dynarmic

The minimum clang/GCC versions we support already support this. We can also
remove is_standard_layout(), as fread and fwrite only require the type to be
trivially copyable.

log: Remove old logging macros and functions

Just a basic update to keep it in sync

travis: Use Xcode 9.3 instead of 9.2

Now that the old macros are no longer used, we can remove all functionality related to them.

gl_shader_decompiler: Add GLSLRegisterManager class to track register state.

core/renderer_opengl: Replace usages of LOG_GENERIC with fmt-capable equivalents

Keeps the toolchains up to date.

general: Convert assertion macros over to be fmt-compatible

Implemented some useful interfaces needed for games.

frontends: Move logging macros over to new fmt-capable ones
