For PR950:

Fix several bugs and update for new assembly syntax. Changes made include:
1. Fixing rules for icmp/fcmp instructions to not require a closing paren
   at the end. This was a cut-and-paste error from a previous commit.
2. Changing things like Out << " " to Out << ' '
3. Adding the "define" keyword for function definitions
4. Adding support for packed structures
