    RISC-V: Use `nullptr' in `riscv_expand_conditional_move'
    
    Use `nullptr' for consistency rather than 0 to initialize `invert_ptr'.
    
            gcc/
            * config/riscv/riscv.cc (riscv_expand_conditional_move): Use
            `nullptr' rather than 0 to initialize a pointer.
    
    (cherry picked from commit 5a21d507561883460411921a291bfd50a9a1d429)
