This corresponds to the parameter-passing convention of the Itanium C++ ABI, in which the argument is passed indirectly and possibly modified, but not destroyed, by the callee. @in_cxx is handled the same way as @in in callers and @in_guaranteed in callees. OwnershipModelEliminator emits the call to destroy_addr that is needed to destroy the argument in the caller. rdar://122707697
