Details of complation and warnings

When I compile my simple file:
#include <clang-c/Index.h>
#include "clang/Tooling/CompilationDatabase.h"
#include "clang/Tooling/Tooling.h"


with the 32-bit Microsoft Visual studio (on Windows 10 64-bit) I get a lot of
warnings like:
E:\Programs\LLVM\llvm-project\llvm\include\llvm/Support/type_traits.h(79):
warning C4624: 'llvm::detail::copy_construction_triviality_helper<T>':
destructor was implicitly defined as deleted
        with
        [
            T=std::string
        ]

The full details can be found in the attachment.

In my case it happens with the 9.0.1. version but I see the same problem with
the current master (1e32df2f91f1aa1f8cd400ce50a621578fa0534e) (could not
complete this build as there was a compilation crash of LLVM / clang) and I've
had a report that it also happens with the 5.0.0 version so it looks like a
long standing problem.
