  Log Message:
  [RISCV] Restrict when RISCVMatInt will retry SLLI as a last step. NFC

The main algorithm will already end with a SLLI when there are 12
or more trailing zeros. We only need to retry when there are less
than 12 trailing zeros since the main algorithm will pick an ADDI
or ADDIW at the end for those cases.
