ConstantExpr - a constant value that is initialized with an expression using other constant values.
This class uses the standard Instruction opcodes to define the various constant expressions. The Opcode field for the ConstantExpr class is maintained in the Value::SubclassData field.

| Instruction * ConstantExpr::getAsInstruction | ( | ) |
getAsInstruction - Returns an Instruction which implements the same operation as this ConstantExpr.
The instruction is not linked to any basic block.
A better approach to this could be to have a constructor for Instruction which would take a ConstantExpr parameter, but that would have spread implementation details of ConstantExpr outside of Constants.cpp, which would make it harder to remove ConstantExprs altogether.
