Bevin Hansson 33bae9c265 [AST] Fix handling of some edge cases in fixed-point division. 
Division by zero was not being handled, and division of
-EPSILON / MAX did not perform rounding correctly.

Bevin Hansson fefa34faf5 [CodeGen] Use the common semantic for fixed-point codegen, not the result semantic. 
Summary:
Using the result semantic is wrong in some cases, such as
unsigned fixed-point + signed integer. In this case, the
result semantic is unsigned and the common semantic is
signed.
