This CL fixes package initialization order by creating the init task before the general deadcode-removal pass. It also changes noder to emit zero-initialization assignments (i.e., OAS with nil RHS) for package-block variables, so that initOrder can tell the variables still need initialization. To allow this, we need to also extend the static-init code to recognize zero-initialization assignments. This doesn't pass toolstash -cmp, because it reorders some package initialization routines. Fixes #43444.
