Cleanup RhExceptionHandling_ functions

Now that nutc generated code does not use them anymore, it is possible to cleanup RhExceptionHandling_ functions to not depend on GetReturnAddress intrinsic.

The binder generate wrappers around checked math helpers were calling RhExceptionHandling_ methods as well. I have changed these checked math helpers to be implemented in C# instead of using the wrappers. It makes them faster (e.g. checked multiplication is 20% faster on x86 now).
