-/// which represent the different flavors of constant values that live in LLVM.
-/// Note that Constants are immutable (once created they never change) and are 
-/// fully shared by structural equivalence.  This means that two structurally
-/// equivalent constants will always have the same address.  Constant's are
-/// created on demand as needed and never deleted: thus clients don't have to
