     [Patch,microblaze]: Optimized usage of pcmp conditional instruction.

     The changes are made in the patch for optimized usage of pcmpne/pcmpeq
     instructions. The xor with register to register is replaced with pcmpeq
     /pcmpne instructions and for immediate check still the xori will be used.
     The purpose of the change is to acheive the aggressive usage of pcmpne
     /pcmpeq instructions instead of xor being used for comparison.
