The motivation is to fix a crash on
struct S {} s;
Foo S::~S() { s.~S(); }
What was happening here was that S::~S() was marked as invalid since its
return type is invalid, and as a consequence CheckFunctionDeclaration() wasn't
called and S::~S() didn't get merged into S's implicit destructor. This way,
the class ended up with two destructors, which confused the overload printer
when it suddenly had to print two possible destructors for `s.~S()`.
In addition to fixing the crash, this change also seems to improve diagnostics
in a few other places, see test changes.
Crash found by SLi's bot.
