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. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
