  -----------
  [RISCV] Use TargetConstant for CSR number for READ_CSR/WRITE_CSR.

This is consistent with what we do for other operands that are required
to be constants.

I don't think this results in any real changes. The pattern match
code for isel treats ConstantSDNode and TargetConstantSDNode the same.
