cmd/compile: canonicalize empty interface types
Mapping all empty interfaces onto the same Type
allows better reuse of the ptrTo and sliceOf
Type caches for *interface{} and []interface{}.
This has little compiler performance impact now,
but it will be helpful in the future,
when we will eagerly populate some of those caches.
Passes toolstash-check.
