Currently these are implemented internally in Clang with the PointerToIntegral cast kind. @davidchisnall suggested that these should really be BitCasts.
I started implementing this but then ran into a few cases where I wasn't sure about what the behaviour should be, such as for case statements. These are in the test cases:

Should there be implicit casts inserted or should the programmer be explicit? If implicit, then what should the behaviour be?
