2bdf1dd58b The changes are made in the patch for optimized usage of pcmpne/pcmpeq instructions. 
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.

	* config/microblaze/microblaze.md (cbranchsi4): Added immediate
	constraints.

0bb87e8a83 The changes are made in the patch for optimized usage of fint instruction. 
The sequence of fint/cond_branch is replaced with fcmp/cond_branch. The
fint instruction takes 6/7 cycles as compared to fcmp instruction which
takes 1 cycles. The conversion from float to int with fint instruction
is not required and can directly compared with fcmp instruction which
takes 1 cycle as compared to 6/7 cycles with fint instruction.

	* config/microblaze/microblaze.md (peephole2): New.
