[PATCH] D41039: Add support for attribute "trivial_abi"

[Akira Hatanaka via Phabricator via cfe-commits]

In CXXRecordDecl::addedMember, set HasTrivialSpecialMembersForCall if Method->isTrivialForCall()  returns true. This fixes a bug where CXXRecordDecl::hasNonTrivialDestructorForCall would return false for the implicit destructor even when the parent class had attribute trivial_abi.

Run test/CodeGenObjCXX/trivial_abi.mm with  -fclang-abi-compat=4.0 to confirm the bug has been fixed.
