merges them together by multiplexing the other operands

35fa7b3057 Fix memory leak when one of multiple DFF cells is removed in opt_rmdff 
When there are multiple DFFs and one of them is removed, its reference lingers
inside bit2driver dict. While invoking handle_dff() function for other DFFs,
this broken reference is used isnside sat_import_cell() function.
