    RISC-V: Add partial instruction display tests
    
    When objdump is specified with a stop address that ends up in the middle
    of an instruction, the partial instruction is expected to be displayed.
    These three tests check that the partial instruction is correctly
    displayed when there are 1, 2, or 3 bytes of the instruction dumped.
