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.
