Artem Dergachev e8ba3ec453 [analyzer] Fix a crash during C++17 aggregate construction of base objects. 
Since C++17, classes that have base classes can potentially be initialized as
aggregates. Trying to construct such objects through brace initialization was
causing the analyzer to crash when the base class has a non-trivial constructor,
while figuring target region for the base class constructor, because the parent
stack frame didn't contain the constructor of the subclass, because there is
no constructor for subclass, merely aggregate initialization.

This patch avoids the crash, but doesn't provide the actually correct region
for the constructor, which still remains to be fixed. Instead, construction
goes into a fake temporary region which would be immediately discarded. Similar
extremely conservative approach is used for other cases in which the logic for
finding the target region is not yet implemented, including aggregate
initialization with fields instead of base-regions (which is not C++17-specific
but also never worked, just didn't crash).
