i965: Do our lowering passes before the loop of optimization.
The optimization loop won't reinsert noise instructions or quadop vectors, so we were traversing the tree for nothing. Lowering vector indexing was in the loop after do_common_optimization() to avoid the work if it ended up that the index was actually constant, but that has been called already in the core.
