* Move a ReturnInst method out-of-line, so that the vtable and type info don't
need to be emitted to every translation unit that uses the class.

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!
