-// ODRHash is used to calculate a hash based on AST node contents that
-// does not rely on pointer addresses.  This allows the hash to not vary
-// between runs and is usable to detect ODR problems in modules.  To use,
-// construct an ODRHash object, then call Add* methods over the nodes that
-// need to be hashed.  Then call CalculateHash to get the hash value.
-// Typically, only one Add* call is needed.  clear can be called to reuse the
-// object.
