Move creation of scopes for primitives into a separate pass

Rather than force scopes to be created for primitives within
InferReactiveScopeVariables, here we move the creation of scopes for these
instructions to a later pass. Later in the pipeline we have more context, such
as whether e.g. a primitive or propertyload is being accessed within a scope or
not, and whether it therefore needs its own scope or not.
