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! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149 91177308-0d34-0410-b5e6-96231b3b80d8
