SILGen: Emit allocating/initializing class ctors.
Add a new SILConstant kind to refer to the initializer of a ConstructorDecl. Emit class constructors as separate allocating and initializing functions named SILConstant(CD) and SILConstant(CD, Initializer) so that derived classes will be able to invoke their superclass constructor.
