📄 Description

Fixes an unreachable in My First Gran Turismo® (CUSA49696)

[Debug] <Critical> scalar_alu.cpp:691 operator(): Unreachable code!
unhandled operand type ExecLo

With this and the other PR I just opened, My First Gran Turismo® (CUSA49696) reaches the title screen (then immediately crashes).

Thanks to @raphaelthegreat for helping.
