[dynarmic] remove reg_alloc from all arguments on x86 emitter (#3150)
From my tests this decreases JIT latency twofold, may be placebo.
saving reg_alloc while having it readily available is certainly a very interesting choice... afterall saving it onto %rdi is way more cheap isn't it? :)
Please test any performance rgressions, I got +20 FPS on Rain World (unlocked) off this change alone
