[RISCV] Slightly improve expanded multiply emulation in getVLENFactoredAmount. (#84113)
Instead of initializing the accumulator to 0. Initialize it on first
assignment with a mv from the register that holds VLENB << ShiftAmount.
Fix a missing kill flag on the final Add.
I have no real interest in this case, just an easy optimization I
noticed.
