llvm/lib/VMCore/iCall.cpp
Chris Lattner 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!
