template simplifier: ignore alias template definitions with syntax errors ( #2169 )
...
Is not allowed to define a type in an alias template definition.
This code:
template<int N>
using A1 = struct B1 { static auto constexpr value = N; };
A1<0> a1;
produces this output:
2: } ;
3: struct B1 { static const auto value = 0 a1 ;
test.cpp:2:57: error: Analysis failed. If the code is valid then please
report this failure. [cppcheckError]
using A1 = struct B1 { static auto constexpr value = N; };
^
because it tries to instantiate the invalid alias template definition
and generates garbage code.

Track lifetime across multiple returns
...
This will now warn when doing something like this:
```cpp
template <class T, class K, class V>
const V& get_default(const T& t, const K& k, const V& v) {
auto it = t.find(k);
if (it == t.end()) return v;
return it->second;
}
const int& bar(const std::unordered_map<int, int>& m, int k) {
auto x = 0;
return get_default(m, k, x);
}
```
The lifetime warning is considered inconclusive in this case.
I also updated valueflow to no tinject inconclusive values unless `--inconclusive` flag is passed. This creates some false negatives because library functions are not configured to not modify their input parameters, and there are some checks that do not check if the value is inconclusive or not.
