symboldatabase: Fix potential null pointer dereference (#1072)
There is a  potential `nullPointer` dereference in symboldatabase. This PR attempts to fix this. Additionally, this could be detected by Cppcheck as well. 

Here is a reduced and compilable testcase, where Cppcheck fails to detect a potential `nullPointer` dereference:

```
class Scope
{
public:
    bool bar();
    int *definedType;
};

int f(Scope *new_scope)
{
    int ret = 1;
    if (new_scope)
    {
        if (new_scope->bar())
        {
            if (!new_scope->definedType) {} // check for null
            ret = *new_scope->definedType; // dereference
        }
    }
    return ret;
}
```

IOBYTE cefb2131c7 Add support for simple c++ 11 type ailases like: using INT = int; (#1024)
* Add support for simple c++ 11 type ailases like: using INT = int;

Only types supported by ValueType are supported. Complex types like
function pointers are not supported. Template type aliases are not
supported.

* Fix crash when type in using type alias is simplified away.

This fixes a crash when size_t is replaced with unsigned long in: using
size_t = unsigned long; by the tokenizer.

This does not fix the problem where Tokenizer::simplifyPlatformTypes()
simplifies away size_t in other cases.  This is only a problem when the
new type is different from the platform type.

is expensive.  Once we determined that a token is not an enumerator,
