  Log Message:
  -----------
  [riscv] Add early return to InsertVSETLI fixed point step [nfc]

If the income state hasn't changed, and the step function is fixed by assumption, then the output state can't have changed.

In the current algorithm, this is a very minor win and mostly allows adding tracing output without being horrible verbose.
