[CIL users] Keep typedefs in casts

[Elnatan Reisner]

CIL sometimes unrolls the type in a cast. This seems to be somewhat inconsistent, though, and keeping the typedefs seems slightly preferable, I think.

For example, given this program:

typedef int myint;
int main() {
        long l = 0;
        myint a = l;
        return a;
}





Elnatan

CIL will cast l to myint at the assignment to a. However, if this cast is present in the source (for example, if you run the output through CIL a second time), the cast to myint gets changed to a cast to int. The attached patch keeps the typedefed type in casts, rather than unrolling to the underlying type.
