[X86] ICMP EQ/NE MIN_SIGNED_INT - avoid immediate argument by using NEG + SETO/SETNO (#94948)
For i64 this avoids loading a 64-bit value into register, for smaller registers this just avoids an immediate operand.
For i8+i16, limit to one use case as we save fewer bytes and these can be wasted entirely on extra register moves.
Fixes #67709
