Philippe Mathieu-Daudé 2dc29222a6 target/mips: Move cpu_mips_get_random() with CP0 helpers 
The get_random() helper uses the CP0_Wired register, which is
unrelated to the CP0_Count register used as timer.
Commit e16fe40c87 ("Move the MIPS CPU timer in a separate file")
incorrectly moved this get_random() helper with timer specific
code. Move it back to generic CP0 helpers.

Aleksandar Markovic 9788e8c9b6 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.

Aleksandar Markovic 256eb7ee58 target/mips: Separate CP0-related helpers into their own file 
For clarity and easier maintenence, create target/mips/cp0_helper.c, and
move all CP0-related content form target/mips/op_helper.c to that file.
