Add new intcc and floatcc operand types for the immediate condition codes on these instructions. Add new IntCompare and FloatCompare instruction formats. Add a generic match_enum() parser function that can match any identifier-like enumerated operand kind that implements FromStr. Define the icmp and fcmp instructions in case.py. Include documentation for the condition codes with these two instructions.
