Correct test cases in the mips backend.

* lib/jit_mips-cpu.c: Correct all current test cases. Call the "xori" not the "XORI" macro for jit_xori implementation, as the XORI macro handles only 16 bit unsigned values. Call the "movr" macro, not the "movi" macro in the special case of adding or subtracting zero. Use the proper temporary register in the jit_andr implementation.
