Explanation:
The clang nodes associated with Swift's Core Foundation types are already represented by a pointer. The interop code does not need to add an extra layer of indirection in those cases.
Scope: C++ Interop
Risk: Very targeted fix for a scenario that was broken before, the code change only affects that scenario.
Testing: Added a regression test.
