  -----------
  [RISCV] Use existing variable intead of calling getOperand again. NFCI

This is a slight change because I'm using the ANY_EXTEND result
instead of the original operand, but getNode should constant fold.

While there, add a comment about why the code specifically checks
for a ConstantSDNode.
