Egor Zhdan 883ff18adb [cxx-interop] Do not crash for void begin() ...

When importing C++ methods, Swift always assumes that methods named `begin()` and `end()` are unsafe, since these methods commonly return iterator types that are inherently unsafe in Swift.

Some additional logic in Sema tries to diagnose usages of `.begin()` and `.end()` from Swift and suggest safe alternatives. That logic had a null pointer dereference bug.
