jens e465dc860b - 'cop_dout' is now generated in pipeline in MEM_STAGE. 
This gives possibility to load cop with memory contents (LWCz).
- dmem_dout can be EX_STAGE.reg_b by default or cop_din if cop_instr_en is asserted.
  This give possibility to store cop content to memory (SWCz)
- removed idecode_rom. Uses opcode_ctrl_lines() directly.
