to compute addresses of branch destinations, so it is not necessary to reserve

Change the chain input of nodes that load the address of a function. This change
...
enables SelectionDAG::getLoad at MipsISelLowering.cpp:1914 to return a
pre-existing node instead of redundantly create a new node every time it is
called.
