This makes all the checks in CheckMemoryLeakNoVar separate functions to
improve readability.

Paul Fultz II c0c6f92221 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]; }
```

Rikard Falkeborn cd36f8ed0a Fix #9253: leakNoVarFunctionCall: do not warn if freopen opens standard stream (#2076)
This fixes false positives from daca@home where freopen is used to
reopen a standard stream. There is no longer a warning for

	void f() {
		assert(freopen("/dev/null", "r", stdin));
	}

rebnridgway d2b9c1f15a Fix some bugs in new Scope Calculation code (#2060)
* Fix for too much information in scope name

When the scope calculation encounters code such as 
"friend class X::Y;"
or
"template<> class X<void> {"
it will now reset the additional name component of the scope that is about to be opened.

* Made sure new scope name is reset after being used

In case there is something like `#define memcpy __builtin_memcpy` in the
