integerOverflow: Separate id for conditional integer overflows

Remove whole program analysis from 'uninitialized variables' and 'null pointer dereference' checkers. I think this logic can more or less be added in ValueFlow instead and then all ValueFlow checkers should get whole program analysis.

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;
}
```

* 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.
