* aarch64-asm.c (aarch64_ins_ldst_reglist): Initialize

        value with a default.
        (do_special_encoding): Likewise.
        (aarch64_ins_ldst_elemlist): Pre-initialize QSsize, and opcodeh2
        variables with default.
        * arc-dis.c (write_comments_): Don't use strncat due
        size of state->commentBuffer pointer isn't predictable.
