    target/mips: Remove identical if/else branches
    
    Remove the segment:
    
          if (other_tc == other->current_tc) {
              tccause = other->CP0_Cause;
          } else {
              tccause = other->CP0_Cause;
          }
    
    Original contributor can't remember what was his intention.
