  Log Message:
  -----------
  [RISCV] Add integer RISCVISD::SELECT_CC to canCreateUndefOrPoison and isGuaranteedNotToBeUndefOrPoison. (#84693)

Integer RISCVISD::SELECT_CC doesn't create poison. If none of the,
operands are poison, the result is not poison.

This allows ISD::FREEZE to be hoisted above RISCVISD::SELECT_CC.
