Akira Hatanaka 5a69c235ae Eliminate the stack slot used to save the global base register. 
The long branch pass (fixed in r160601) no longer uses the global base register
to compute addresses of branch destinations, so it is not necessary to reserve
a slot on the stack.

Akira Hatanaka 35792089e7 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.
