Avoid retyping of Literals
Literals need to be promoted as is, because constant folding might
have changed the type of the literal to the expected type. E.g. in
val x: Byte = 2
The literal 2 will have type `Byte(2)` but its underlying constant will still be `Int(2)`.
So re-typing would give the wrong type.
