mips_ite interface is implemented by the CPU, for
communicating with the MIPS Inter-Thread Communication Unit.
The set_dtag_lo function sets the DTagLo SPR.
The get_dtag_lo function returns the value of the DTagLo SPR.
The get_errctl function returns the value of the ErrCtl SPR.
The block_tc function marks the current TC as blocked on gating storage and swaps in another TC.
The gated_exception function throws an immediate exception.
The current_tc_num function returns the currently running TC number on the VPE.
The unblock_tc function unblocks the specified TC if it is currently blocked on gating storage.
The is_big_endian function indicates if the CPU expects big endian memory storage.
