 1. Add FAdd and FSub conditions in is_add_op function in opcode_func.cpp  : Previously, Floating-point add/sub are not considered for power estimation  So, Adder power looks very low for floating-point workloads
 1. Add FAdd and FSub conditions in is_add_op function in opcode_func.cpp
 : Previously, Floating-point add/sub are not considered for power estimation
 So, Adder power looks very low for floating-point workloads

 2. Removed shifter conditions out of is_bit_op function
 : We modeled shifter and bit operations differently
