[analyzer] Teach CallEventManager that CXXTemporaryObjectExpr is also a ctor.

Specifically, CallEventManager::getCaller was looking at the call site for
an inlined call and trying to see what kind of call it was, but it only
checked for CXXConstructExprClass. (It's not using an isa<> here to avoid
doing three more checks on the the statement class.)

This caused an unreachable when we actually did inline the constructor of a
temporary object.
