Made the following changes:

* ValueHolder became a 3 argument template. This allows for BasicBlock to
use the value holder arg as a typesafe parent pointer.
* SymTabValue no longer inherits from Value
* Method does not inherit from only SymTabValue. Now it inherits from both
STV & Value.
* Module does not inherit from only SymTabValue. Now it inherits from both
STV & Value.
* Updated the SymTabValue.h file to reference SymTabValue instead of STDef
in several places
* Added isArraySelector & isStructSelector to GetElementPtr instruction
