dc4c3f2f5f 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

c8b25d40cb Changed the fundemental architecture of Operands for Instructions. Now 
Operands are maintained as a vector<Use> in the User class, and operator
iterators are provided as before.  Getting an operand no longer requires
a virtual function call.

WARNING: getOperand(x) where x >= getNumOperands() will now assert instead
of returning null!

4dd88f6fbf Big changes. Interval*.h is now more or less finalized. IntervalPartition 
is recoded to use IntervalIterators.  IntervalIterators can now maintain
their own memory or let an external entity do it.

Loop depth is a new user of IntervalPartition for calculating the loop
nesting depth of a basic block

TODO: add IntervalPartition capability to split intervals between the looping
portion and the "tail" portion.
