Jon Ross-Perkins d944347e7b Elide prelude components in the IR formatter. (#4453)
This is in particular to avoid churn from changes such as #4370. I think
the import list can be helpful (particularly to understand what the
library is aware of), but it's a different trade-off for the prelude
package due to the implicit imports.
