Takuya Shimizu 0c9c9dd9a2 [clang][Sema] Add truncation warning on fortified snprintf ...

This patch warns on snprintf calls whose n argument is known to be smaller than the size of the formatted string like

```
char buf[5];
snprintf(buf, 5, "Hello");
```
This is a counterpart of gcc's Wformat-truncation
