Split up monolithic Regs struct

externals: nihstro, update to latest master. Again.

Use std::array<u8,2> instead of u8[2] to fix MSVC build

IPC helper

Oh No! More shader changes!

Texture decoding cleanups

I changed the macro in microprofileui.h from WIN32 to _WIN32 so that it
would correctly dectect that its being compiled on a windows platform

Core: update Kernel Config Memory to latest version (11.2)

ShaderJIT: add 16 dummy bytes at the bottom of the stack

arm_dynarmic: Coprocessor support

removed the possibly uneeded cast on values.gdbstub_port

removal of the -1 case in the configure_input switch

as far as i could tell this cast is unneeded because [GDBStub::SetServerPort](https://github.com/citra-emu/citra/blob/master/src/core/gdbstub/gdbstub.cpp#L897) takes a u16 and [values.gdbstub_port](https://github.com/citra-emu/citra/blob/master/src/core/settings.h#L116) is already a u16

this case is unneeded because no enumeration value can possibly correspond to it

This allows Phoenix Wright - Dual Destinies to boot.

These are not used any more since we moved shader JIT to xbyak.
