By combining the load+op, we may force the op to happen earlier in the store chain. That might force the SymAddr operation earlier, and in particular earlier than its corresponding VarDef. That leads to an invalid schedule, so avoid that. This is kind of a hack to work around the issue presented. I think the underlying problem, that LEAQ is not directly ordered with respect to its vardef, is the real problem. The benefit of this CL is that it fixes the immediate issue, is small, and obviously won't break anything. A real fix for this issue is much more invasive. The go binary is unchanged in size. This situation just doesn't occur very often.
