5a2d2b1f0a 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

d6c5a769ea Don't clean out the type plane of the constant pool... this is a hack. FIXME

b1ca9cbceb Broad superficial changes: 
* Renamed getOpcode to getOpcodeName
* Changed getOpcodeName to return a const char * instead of string
* Added a getOpcode method to replace getInstType
* Changed code to use getOpcode instead of getInstType

a073acb22d 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!

81f3ace753 IntervalPartition was changed to inherit from vector<Interval*> instead of 
contain it so that it would have full iterator access without much work.
