Fix issue 8431 and 8776: Size of constant string
...
Fixes these cases:
```cpp
void f(void) {
const std::string msg="xyz";
if(!msg.empty()){} // Always true
}
```
And out of bounds access:
```cpp
#include <string>
char fstr1(){const std::string s = "<a><b>"; return s[42]; }
wchar_t fwstr1(){const std::wstring s = L"<a><b>"; return s[42]; }
```
