Martin Whitaker eb2a9be0c9 Fix for br999 - incorrect result from binary comparison. 
When a binary (in)equality comparison has a constant left operand,
the tgt-vvp code generator swaps the left and right operands to
allow the cmpi instruction to be used. The code for swapping the
operands was incorrect.

Stephen Williams 63ad15ee2e Rework user function calls to use specialized opcodes. 
Create The %callf/* opcodes to invoke user defined functions in a
more specialized way. This allows for some sanity checking on the
way, and also is a step towards keeping return values on stacks.
