autovarInvalidDeallocation: Fix fp with impossible value (#3604) 
daca reports new false positives after db4f94fdfe on the form:

	void f() {
	    char *ptr = malloc(10);
	    char *empty_str = "";
	    if (ptr == NULL)
	        ptr = empty_str;
	    if (ptr != empty_str)
	        free(ptr);
	}

Add a check that the value is not impossible to avoid this.

Don't simplify template for class names in declarations (#3505) 
* Don't simplify template for class names in declarations

Without the patch, the test would give:

```
Expected:
namespace foo { class Bar ; } class Baz ; class C : Baz { } ;

Actual:
namespace foo { class Bar ; } class Baz ; class foo :: Bar : Baz { } ;

```

* Use valid code in test case
