    Fix PR 109919: ICE in emit_move_insn with some bit tests

    The problem is I used expand_expr with the target but
    we don't want to use the target here as it is the wrong
    mode for the original expression. The testcase would ICE
    deap down while trying to do a move to use the target.
    Anyways just calling expand_expr with NULL_EXPR fixes
    the issue.

    Committed as obvious after a bootstrap/test on x86_64-linux-gnu.
