Version v2 uses movsi/di for GOT accesses until after reload as suggested. This
caused worse spilling, however improving the costs of GOT accesses resulted in
better codesize and performance gains:
Improve GOT addressing by treating the instructions as a pair. This reduces

Sorry, I guess I'd not given enough wei
