Return true if the specified constant can be handled by the code generator.

We don't want to generate something like: void *X = &X/42; because the code generator doesn't have a relocation that can handle that.

This function should be called if C was not found (but just got inserted) in SimpleConstants to avoid having to rescan the same constants all the time.
