Rikard Falkeborn abea580b78 Fix FP memory leak with unknown function call in condition (#2012)
* Fix FP memory leak with unknown function call in condition

This was introduced in 8513fb81d2 when
fixing memory leaks for global variables allocated in condition. The
refactored code had an inconsistency where c and c++ code behaved
slightly differently when `var` is NULL. This seemed to not have an
impact as the code was written prior to 8513fb81d2,
but when the same code was used for conditions, FPs were introduced.

The introduced FPs were memleak warnings when there should have been an
information message about missing configurations for code like

	void f() {
		char *p = malloc(10);
		if (set_data(p)) {}
	}

Fix this by always returning true if varTok->Variable() is NULL for
both c and c++ code.

* Improve function name

Paul Fultz II a08a9c1349 Switch to use lifetime analysis for iterators and pointers to invalid containers
This will diagnose more issues such as:

```cpp
void f(std::vector<int> &v) {
    auto v0 = v.begin();
    v.push_back(123);
    std::cout << *v0 << std::endl;
}
```
