IRGen: Add initializeValueWitnessTable to TypeInfo. For dynamic generic types, this emits the sequence of operations to turn a value witness table template into a full, valid value witness table. For now, leave it stubbed out as empty, except for dynamic singleton unions, where we copy the size, flags, and stride from the lone element's table. Swift SVN r8014
