    Re: Optimise away eh_frame advance_loc 0

    If we happen to get the fixed and variable parts of the advance_loc
    in different frags, bad things happen when subtracting one from a
    fr_fix of zero.

        PR 25125
        * dw2gencfi.c (output_cfi_insn): Don't allow DW_CFA_advance_loc4
        to be placed in a different frag to the rs_cfa.
