[PATCH] D135557: Add needsImplicitDefaultConstructor and friends

I would be more comfortable with exposing something like `clang_CXXRecord_hasAnyNonDeletedDefaultConstructor`. It's better than the confusing `clang_CXXRecord_needsImplicitDefaultConstructor` but it would still be different from the usual type traits in a subtle way. For the other special member functions that would be enough, we can use `!CXXMethod::isIneligibleOrNotSelected()` to know if their constraints are satisfied and there's no SFINAE problems because except for default constructors they're not allowed to be templates.
