Fix for case when vector iterator is raw pointer
We are using patched libc++ which uses raw pointers for vector itrators to improve code compilation speed. This commit fixed two compilation issues in toml11: * location::const_iterator deinition assumes that vector const_iterator is struct or class type rather than raw pointer. * `const const_itetr foo()` triggers `-Wignored-qualifiers` for primitive types and `void` which breaks `-Wextra -Werror` compilation.
