Fix 9546: properly check that the bound is the size ( #2475 )
...
Previously, as the check was done on the token and not on the ast,
`i <= v.size()` and `i <= v.size() - 2` would both raise the same
warning.
This patch fixes this, but this mean the check is only done when the
condition if `i <= v.size()`. Any other (more complex) condition is
ignore, and so we have false negative for instance with
`i <= v.size() + 1`.

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.
