    riscv disassembler leak
    
    Commit 3f61a38b5e81 moved the disassembler subset_list from a static
    variable to disassembler private_data.  It is now malloc'd in
    riscv_init_disasm_info so should be freed when disassemble_free_target
    runs.
    
            * riscv-dis.c (disassemble_free_riscv): Free subset_list.
