* Fix #8382 (Syntax error when scanning code with template and attribute)

This commit only addresses #8382. There are issues concerning which
versions of C++ should be supported and also generic C++ 14 attribute
support which can be revisited later.

* Remove all C++ style attributes.

Remove all C++ style attributes when C++ version is 11 or greater.
Rename simplify function to simplifyCPPAttributes.
Handle more cases of roreturn function attribute.

Jørgen Kvalsvik a61f21d1b6 Accept nested templates in tokenizer-simplify (#1070)
The following snippet triggerd the error:

template<typename DerivedT>
template<typename T>
auto ComposableParserImpl<DerivedT>::operator|( T const &other ) const -> Parser {
    return Parser() | static_cast<DerivedT const &>( *this ) | other;
}

Whenever simplifyFunctionParameters was called on a templated class'
templated member function (and probably any nested template), the
tokenizer would recognise it as a syntax error, assuming that return
type *must* come after a template<> token.

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;
}
```

David Hallas 4d18d3948f Fixes issue with case inside switch that is not a compound statement (#1031)
* Fixes issue with case inside switch that is not a compound statement was treated as garbage

This fixes an issue with the check for case keywords outside of switch
detection that would treat a case statement inside a switch that is not
a compound statement as garbage, but this is perfectly valid C++. This
construct is used in several libraries, i.e. Google Test.

* Tweak check and handle missing semicolon

Tweaks the check with feedback from danmar.
Handle the case where there is no semicolon and document it with a unit
test.
