ce8eb0c16b Add a new option to indicate we want the code generator to emit code quickly,not spending tons of time microoptimizing it. This is useful for an -O0style of build.

this, feel free to convert the rest over, if you hate it, feel free to
revert.

still lots of uglyness.
Maybe calls will come soon.
Fixing the return value of things will be necessary to make alpha work.

3e2bafd640 Add FP versions of the binary operators, keeping the int and fp worlds seperate. 
Though I have done extensive testing, it is possible that this will break
things in configs I can't test.  Please let me know if this causes a problem
and I'll fix it ASAP.

ending up in the resultant function constant pool.
