[LLVMdev] C++ Constructors

In general, it should be "priority" of the ctor. Runtime traverses the
list of ctors from beginning to end. Thus, sorting the array of ctors
and emitting them in some specified order - we can force one ctor to
be run after another. This integer (see, e.g. gcc docs for
'constructor' attribute) should introduce such priority order.

I don't remember offhand, whether it's currently properly implemented,
or not....
