Memory::AddressSpace is where a CPU's addresses point (base) and its block
shadow, with the unchecked accessors and block shadow helpers as methods. The
main CPU's is Memory::g_mainSpace, kept in step with Memory::base and
blockShadow, and MIPSState::space points at it.
The CPU cores now go through their state's space instead of the globals: the
interpreter's and IR interpreter's loads and stores (which also saves the IR
interpreter reloading the global base), the IR interpreter's block lookup,
the block table's shadow entries, and the native JITs' memory base register,
block shadow lookups and pointerified registers. Address validity and
everything outside the cores still use the globals.
No change for the main CPU; this is so another CPU (the Media Engine) can see
memory differently. Benchmarked against master (God of War: Chains of
Olympus, Tekken 6): JIT instructions retired within noise, IR interpreter
2% fewer.

HLEFunc and ReplaceFunc now take the MIPSState they run on. The dispatch
paths (both interpreters and every JIT backend) pass in the state they
belong to, and CallSyscall*, hleFinishSyscall and the HLE mips call
machinery use it instead of currentMIPS.
The wrappers in FunctionWrappers.h take the function as `auto` and call it
through HLECall, which also accepts an implementation with an extra leading
MIPSState * parameter and passes the state to it. Any other signature still
fails to compile, as before. PARAM/RETURN now refer to a local `mips`.
The HLE functions (and replacement functions) that used currentMIPS now take
the state that way. Callers outside a syscall's own frame - CoreTiming
events, the adhoc matching thread, dialogs, PPGe, the debugger UIs - pass
currentMIPS or &mipsr4k explicitly. The kernel's thread internals still use
currentMIPS.

The JIT backends' calls out of generated code (the MIPS and IR interpreter
fallbacks, and the bad address report) now take the state the backend was
built for instead of reading currentMIPS. Likewise the interpreter's tick
check, the IR dispatcher's Advance, and a couple of debugger helpers.
MIPSState::InitRegisters() no longer sets currentMIPS; the boot paths set it.
