* Fix 9392, but for destructors: out-of-line defaulted destructors skipped everything after
Context:
```
struct S {
~S();
};
S::~S() = default;
void g() {
int j;
++j;
}
```
Everything after `S::~S() = default;` was skipped, so the uninitialized variables in g() weren't found.
Out-of-line destructors are useful e.g. when you have a forward declared unique_ptr in the .h,
and `= default` the destructor in the .cpp, so only the cpp needs to know the header for destructing
your unique_ptr (like in the pImpl-idiom)
* Fix unit test, by correctly fixing 10789
Previous commit broke this test, but also provided the tools for a cleaner fix
* Document current behaviour
* Rewrite control flow
* Fix deleted functions, which skipped everything after
`a::b f() = delete` triggered the final else in SymbolDatabase::addNewFunction,
which sets tok to nullptr, effectively skipping to the end of the stream.
* Remove troublesome nullptr, which skips every analysis afterwards
It was introduced in 0746c241 to fix a memory leak.
But setting tok to nullptr, effectively skipping to the end, seems not needed.
Previous commits fixes prevented some cases where you could enter the `else`.
This commit is more of a fall back.
