This seems to be a GNU libc extension; we offer a fixit to %lld on
these platforms.

This is useful for example for %n in printf, which expects
a pointer to int with the same logic for checking as %d
would have in scanf.

Warn about using pointers to const-qualified types as arguments to
scanf. Ignore the volatile qualifier when checking if types match.

This makes Clang check that the corresponding argument for "%n" in a
format string is a pointer to int.

This is in preparation for being able to warn about 'q' and other
non-standard format string features.
It also allows us to print its name correctly.

Before r148025 we (accidentally) didn't check whether a length modifier is
appropriate for a scanlist, but now we do.

string is part of the function call, then there is no difference. If the
format string is not, the warning will point to the call site and a note
will point to where the format string is.
Fix-it hints for strings are moved to the note if a note is emitted. This will
prevent changes to format strings that may be used in multiple places.
