Require the two-argument MI::addOperand(MF, MO) for dangling instructions.

Browse Source 
Instructions that are inserted in a basic block can still be decorated
with addOperand(MO).

Make the two-argument addOperand() function contain the actual
implementation. This function will now always have a valid MF reference
that it can use for memory allocation.
