Implement std::is_base_of for the case where we don't have a compiler intrinsic. This relies upon the fact that overload resolution does not check access and ambiguity for a derived-to-base conversion. This passes all is_base_of tests in the test suite. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@170662 91177308-0d34-0410-b5e6-96231b3b80d8
