Summary: bad_function_call is currently an empty class, so any object files using that class will end up with their own copy of its typeinfo, typeinfo name and vtable, leading to unnecessary duplication that has to be resolved by the dynamic linker. Instead, give bad_function_call a key function and put a definition for that key function in libc++ itself, to centralize the typeinfo and vtable. This is consistent with the behavior for other exception classes. The key functions are defined in libc++ rather than libc++abi since the class is defined in the libc++ versioning namespace, so ABI compatibility with libstdc++ is not a concern. Guard this change behind an ABI macro, since it isn't backwards compatible (i.e., clients built against the new libc++ headers wouldn't be able to run against an older libc++ library).
