Henrik RydgårdandClaude Fable 5.1 e0f09c55d5 MIPS: INT_MIN / -1 leaves HI at zero, like the hardware ...

Every path special-cased the one signed division overflow and set the
remainder to -1. cpu/cpu_alu/cpu_div, recorded on a PSP, says it's 0.
The classic arm64 JIT was the only one that got it right, by not
special-casing it at all.

arm64, RISC-V and LoongArch all produce INT_MIN with remainder 0 natively,
so their fixup blocks go away. x86 has to keep the check (IDIV traps) but
sets HI to 0 now, and so do both interpreters.
