Lazy bingding for region-store manager.
* Now Bind() methods take and return GRState* because binding could
also alter GDM.
* No variables are initialized except those declared with initial
values.
* failed C test cases are due to bugs in RemoveDeadBindings(),
which removes constraints that is still alive. This will be fixed in later
patch.
* default value of array and struct regions will be implemented in later patch.
