Define icmp and fcmp comparison instructions.

Browse Source 
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.
