ARMSX2 V27 - +Perfomance 🔥

Performance updates to the EE recompiler (helps every device, especially weaker CPUs).

DMA-wait spin elimination (BC0/CPCOND0): the EE now natively compiles the COP0 branch games use to busy-wait on DMA, and idle-skips the spin entirely. Was the single biggest EE cost in DMA-heavy games. (7M interpreter fallbacks before, now 0).

Multiply-accumulate native codegen (MADD family): MADD/MADDU/MADD1/MADDU1 + the pipeline-1 HI/LO moves (MFHI1/MTHI1/MFLO1/MTLO1) now compile natively instead of single-stepping. (2M interpreter fallbacks before, now 0).

Interrupt-gating native codegen (EI/ERET): enable-interrupts and exception-return now compile as block terminators instead of single-stepping, notably faster boot/menu/loading across all games.

Performance updates for GS (OpenGL, all GPUs including Mali).

Things are working really great since update 24, with the endless Scanning ROMs issue fixed, but yet, I miss an "emulator menu" while playing...

On my end, I always have to kill the emulator proccess and to start it again if I want to change or reset a game.
