[PATCH] D25448: [ubsan] Use the object pointer's type info for devirtualized calls

Thanks for the feedback!

Patch update:

- Pass in the right CalleeDecl to EmitCXXMemberOrOperatorCall. This lets us drop the unnecessary 'DevirtualizedClassTy' optional parameter.
- Extend the test case with John's example (devirt for methods marked 'final'). Since this hasn't yet been implemented in clang, make the checks depend on the relevant bug (PR13127).

Tested with check-ubsan and check-clang.
